Extended data: the algorithm of vertical fractional division;

A divider is the division of decimals. First, move the decimal point of (divisor) to become (integer). Such as 0.756 ÷ 0.18 = 75.6 ÷18 = 4.2.

The decimal point of the divisor is moved several digits to the right, and the decimal point of the dividend is also moved (several digits) (there are not enough digits, so "0" is used at the end of the dividend); Then it is calculated by fractional division with divisor (integer). 3.3÷0.75=330÷75=4.4。

When dividing by integer, the decimal point of quotient should be aligned with the decimal point of dividend. In the division formula, where is the quotient written except the dividend, that is to say, the dividend is aligned with the same digit of the quotient, and the same digit is aligned only when the decimal point is aligned, so the decimal point of the quotient should be aligned with the decimal point of the dividend.
