1, the decimal point of the quotient is aligned with the decimal point of the dividend.

2. The most significant bit of the integer part cannot be 0. But if the integer part is not quotient 1, quotient 0.

3. The middle of the decimal part of the quotient must be quotient 0.

The second case: both dividend and divisor are decimals.

First, the divisor is converted into an integer (that is, the dividend and the divisor are expanded by the same multiple at the same time), and then the division operation is carried out.
