1, dividend and divisor are integers:
Integer division requires that both dividend and divisor are integers and the value is not zero. This means that in integer division, we need to ensure that the dividend and divisor are integers and their values are not zero. For example, if we want to divide 10 by 3, then the dividend is 10 and the divisor is 3, which are all integers.
2. Divide from high dividends:
In integer division, we usually start the division from the high order of dividend. This means that we should consider the highest dividend first, and then consider it in turn. For example, when calculating the division of 10 by 3, we start from the highest bit of the dividend, that is, from the tenth place of 10, and then put the quotient in the tenth place of the result.
3. Divider should be less than dividend:
The divisor in integer division must be less than the dividend. This is because if the divisor is greater than or equal to the dividend, then the quotient will not be able to obtain the integer value. For example, when 10 is divided by 3, because 3 is less than 10, it can be concluded that the quotient is 3 remainder 1. This rule ensures the correct division of integers and is widely used in mathematics.
4. The quotient should face the unit of dividend:
In integer division, quotient points to the unit of dividend. This means that in the calculation process, the quotient should be placed in the correct position, that is, the unit of dividend. For example, if we divide 10 by 3 and put the quotient in one place, we get the result of 3 remainder 1.
5, the remainder is less than the divisor:
The remainder in integer division must be less than the divisor. This is because if the remainder is equal to or greater than the divisor, the quotient can be increased by 1. For example, if 10 is divided by 3, the remainder is 1. Because 1 is less than 3, the quotient is 3 remainder 1. This rule can be used to ensure the correctness of calculation results and is widely used in mathematics.
