2. Explain the math clearly. Division is actually division and average. Division with remainder means that the remainder is less than 1 at the end of division. Average score, then if the quotient is less than 1, it is 0, and the percentage is not enough, then divide by ten. In the process of division, we should start from the highest bit and divide one bit into lower bits, that is, we should start from the highest bit until the last bit-one bit.
3. Some special division calculations. It should be noted that some divisions have special formats in the process of writing. For example, if there is a division of 0 in the middle of quotient, you can skip the process of quotient 0, but quotient 0 must be written. Also, when there is a 0 at the end of the quotient, the process of quotient 0 can also be skipped. However, it should be noted that since the last paragraph of quotient 0 is skipped, after calculating the last non-zero bit of quotient, 0 should be written.
