Law of division:

Remember that all items in the divisibility of numbers should be integers. But the divisor is not equal to 0, and the quotient is an integer with no remainder. When a÷b, it can be said that number B can be divisible by a, number A can be divisible by b, a is a multiple of number B, and b is a divisor of number A. If you ask for a divisor, you must remove the natural number, and if you ask for a multiple, you must multiply it by the natural number.

Bits divisible by 2, 5 and 3 are 0 and 5, and must be divisible by 5. The units are 2, 4, 6, 8 and 0, and they must be divisible by 2. If the sum of each number is a multiple of 3, it must be divisible by 3.
