Notice:

When dividing a two-digit number by a one-digit number, you must divide from the ( ) of the dividend; whichever digit of the dividend you divide to, ( ) is written above that digit.

The same point: they all start from dividing by the number in the tens digit of the dividend. The quotient is written on which digit of the dividend is divided.

The difference: Example 2 is that there is a remainder in the tens digit of the divided number, which must be combined with the number in the ones digit before dividing.

When dividing a two-digit number by a one-digit number, you must start from the division of the dividend ( ); whichever digit of the dividend you divide to, ( ) is written above that digit. If there is ( ) after division of any digit of the dividend Note that ( ) is smaller than the divisor, add ( ) and the next digit of the dividend to continue dividing.

A: Starting from the high digit of the dividend, each time the divisor is used, first try to divide the previous digit of the dividend. If it is smaller than the divisor, then try to divide the first two digits.

B: Whichever digit of the dividend you reach after dividing, write the quotient above that digit.

C: Every time a quotient is found, the remaining number must be smaller than the divisor.
