Write the quotient on the number except the dividend. If the divisor is not enough, put the quotient on this number.

The remainder of each division must be less than the divisor, put the digits of the dividend in the right of the remainder, and then continue the division.

Extended data

For example, 42 divided by 7:

42 is divided from the first ten digits of 4, and 4 cannot be divided by 7. Then divide by combining the first ten digits with the last one, that is, combine 4 and 2 into a number. Divide 42 by 7, and the quotient is 6. Then 42÷7=6.
