R9480 computing power

88 ÷ 4 = 22, the column vertical formula is as follows:

1. Write 22, 4, vertical multiplication sign according to the vertical calculation format

2. According to the multiplication algorithm, starting from the last bit

indivial position: 2 × 2 = 4, do not carry, just write down the number 4 on the digit

3, on the 10th: 2 × 2 = 4, no carry, also write down the number 4 on the ten

4, that is 22 × 4 = 88, and 88 ÷ 4 = 22, the calculation is correct, and the verification is passed

Division Rules for integers

1) starting from the high position of the divisor, first look at how many digits the divisor has, and then try to divide the first few digits of the divisor by the divisor, if it is smaller than the divisor, try to divide more digits

3) after each division, the remaining number must be smaller than the divisor
