1. Three digit divided by one digit example 817 ÷ 4
solution idea: divide each digit of the divisor from the high position, keep the quotient of each calculation, and add the remainder to the next digit to calculate, so the divisor will be calculated in this order, and the quotient will be combined in order, and the remainder will be the last operation result
solution process:
Step 1: 8 ÷ 4 = 2, the remainder is: 0
Step 2: 1 ÷ 4 = 0, the remainder is 1
Step 3: 17 ÷ 4 = 4, the remainder is: 1
according to the above calculation steps, the combination result quotient is 204, and the remainder is 1
checking calculation: 204 × 4 + 1 = 817
extended data & checking results: four operation rules (calculation in sequence, multiplication and division first, addition and subtraction second, brackets first, multiplication and square first) that is, disjunction operation (recursive equation calculation) should be carried out under the premise of this principle
problem solving process:
204 × 4 + 1
= 816 + 1
= 817

Divide from the hundreds. If the number on the hundreds is not enough, divide by the first two digits of the divisor. When there is not enough remainder in the division, divide the remainder and the number on the next digit of the divisor by the divisor. The remainder of each division must be smaller than the divisor
the following example is 564 ÷ Two column vertical:
If AB = C (B ≠ 0), the operation of finding another factor A by using proct C and factor B is division. Write C / B and read C divided by B (or B divided by C). Where C is called the divisor, B is called the divisor, and the result of the operation a is called the quotient
extended data:
the divisor divided by two divisors is equal to the proct of the two divisors. Sometimes we can carry out simple operations according to the nature of division. For example: 300 ÷ twenty-five ÷ 4=300 ÷ twenty-five × 4) Divide by a number = the reciprocal of the number
the divisor expands (shrinks) n times, the divisor remains unchanged, and the quotient expands (shrinks) n times correspondingly. The divisor expands (shrinks) n times, the divisor remains unchanged, and the quotient shrinks (expands) n times correspondingly
3. Three digit divided by one digit example analysis 382 ÷ 5
solution idea: divide each digit of the divisor from the high position, keep the quotient of each calculation, and add the remainder to the next digit to calculate, so the divisor will be calculated in this order, so the quotient will be combined in order, and the remainder is the last operation result
solution process:
Step 1: 38 ÷ 5 = 7, remainder: 3
Step 2: 32 ÷ 5 = 6, the remainder is: 2
according to the above calculation steps, the combination result is 76, the remainder is 2
checking calculation: 76 × 5 + 2 = 382
extended data [checking result]: four operation rules (calculation in order, multiplication and division first, addition and subtraction second, bracket first, multiplication and square first) that is, disjunction operation (recursive equation calculation) should be carried out under the premise of this principle
problem solving process:
76 × 5 + 2
= 380 + 2
= 382
if in doubt, please ask, if satisfied, please adopt

4. Now, we could just just just just just divisible 3 3. So we get 1. So we could just just just just, we could just just just just just, we could just just just just just just, we could just just just just just just just just just, we have 955 divided 5. Now, 490 divided 7. Now, 490 divided 7. So, 490 divided 7 is 240. Now, we're just just just just just just just just, we have the 6. Now, we're just just just just just just just just just just just, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have, we have 7 is 540 divided by 6. 320 divided by 4 is 540 divided by 3. 444 divided by 6 is 640 divided by 4. 606 divided by 6 is 279 divided by 9.

6. The result of dividing three digits by one digit may be two digits. It could be three digits, like 300 ÷ 5 = 60
1. Cultivate good interest in learning
as the saying goes: interest is the best teacher. Only when you have interest can you have a hobby. Only when you like it can you practice it. Only when you enjoy it can you form the initiative and enthusiasm in learning. Naturally, I will be determined to learn mathematics well and become a success in mathematics learning. Even Confucius once said: those who know are not as good as those who are good, and those who are good are not as happy as those who are
“ "Good" and "happy" are willing to learn and like to learn, which is interest
2. Cultivate good study habits
many students with poor mathematics performance or poor foundation do not have a good study habit. Good study habits will make your study feel orderly and relaxed. The good study habits of high school mathematics should be: more questioning, diligent thinking, good hands-on, heavy inction, and attention to application. In the process of learning with the teacher's steps, we should cultivate the ability to translate what the teacher says into our own special language and remember it in our mind forever
3. Pay attention to listening in class and review in time after class
the mastery of mathematical knowledge comes from the classroom, so we should pay special attention to the learning environment in class and seek the correct learning methods In class, we should follow the idea of doing things closely, actively carry out the following steps of thinking prediction, and compare our thinking of solving problems with what the teacher said. Review in time after class, leaving no doubt. Before doing all kinds of exercises, recall the knowledge points that the teacher said. Finish the homework carefully and independently. We should develop a learning style of not always asking questions.
