One points, one is not enough to see two. In addition to which business, which one is not enough to occupy a zero position. After each division, the remainder is less than the divisor. Operation formula: dividend-divisor = quotient; Dividend quotient = divisor; Quotient * Divider+Remainder = Divider.

Thinking of solving problems: Starting from the highest bit of 4, the quotient of 4 divided by 4 is 1, and then the second quotient of 2 divided by 9 is 1. Finally, the last bit of 2 and the remainder array of 1 obtained in the previous step are combined into a number 12, which is divided by 4, and the quotient is 3, and finally the result of 492÷4 is obtained.

Definition of division:

Division is an operation method in mathematics. The simplest is the division of numbers, which is a simple algorithm of subtracting several identical numbers from one number. If you subtract the same number 2 from 10, you can subtract 5 from the total number * * *, that is, 10 divided by 2 or 2 divided by 10. Given the sum of the products of two numbers, it can be said that division is the inverse of multiplication.

Division of two numbers is also called the ratio of two numbers. If ab=c(b≠0), the operation of finding another factor A by multiplying the product C and the factor B is division, which is marked as c÷b and pronounced as C divided by B (or B divided by C). Among them, c is called dividend, b is called divisor, and the result of a operation is called quotient.
