The method of dividing two digits by one digit is as follows:

1, first determine how many digits the quotient is.

If the ten digits of the dividend are less than the divisor, the quotient is a single digit. Business is written in a Viteri.

If the ten digits of the dividend are greater than or equal to the divisor, the quotient is two digits. The first place of quotient is written in the tenth place.

2. Trial operation. (What can I fill in at most)

3. If the quotient is two digits, divide it by ten digits first, and then divide it by divisor after the combination of remainder and single digits.

4. The remainder must be less than the divisor.

The purpose of extended data division is to find the quotient, but when you can't see how many quotients are contained in the dividend at once, you can try to estimate the quotient, see how many divisors are contained in the most significant bit of the multiplicand (that is, how many times the quotient is contained), and then add several times the complement from the standard number to get the quotient.

Small array: When the dividend contains divisor 1, 2, 3 times, the period method is:

Dividend includes quotient 1 multiple: the complement is added once from the standard.

Dividends include two quotients: from standard to supplementary.

Dividends include three quotients: from standard to supplementary three times.
