Decimal division calculation rules:

First, move the decimal point of the divisor to make it an integer, then move the decimal point of the divisor to the right by several digits (if there are not enough digits, add "0"), and then calculate according to the division rule that the divisor is an integer.

Properties of decimals:

1, add or delete any zeros at the end of the decimal, and the size of the decimal remains the same. For example: 0.4=0.400, 0.060=0.06.

2. Move the decimal point to the right (or left) by n digits respectively, and the value of the decimal point will be expanded (or reduced) by n times.
