Division is one of the four operations. Given the product of two factors and a non-zero factor, the operation of finding another factor is called division. 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.

Properties of division operation
(1) If a number is divided by (or multiplied by) a number and then multiplied by (or divided by) the same number, the number remains the same. For example: 68÷ 17× 17=68 (or 68× 17÷ 17=68).
(2) A number divided by the product of several numbers can be divided by the factors in the product in turn. For example: 320÷(2×5×8)=320÷2÷5÷8=4.
(3) The quotient of a number divided by two numbers is equal to the number divided by the dividend in the quotient and then multiplied by the divisor in the quotient. For example: 56÷(8÷4)=56÷8×4=28.
(4) The product of several numbers is divided by a number, so that any factor in the product can be divided by this number and then multiplied by other factors. For example: 8×72×4÷9 = 72÷9×8×4 = 256.
If the sum of several numbers is divided by a number, you can divide each addend by this number first, and then add up each quotient. For example: (24+32+16) ÷ 4 = 24 ÷ 4+32 ÷ 4+16 ÷ 4 =18.
6. If the difference between two numbers is divided by a number, the quotient obtained by dividing the minuend by this number can be subtracted from the quotient obtained by dividing the minuend by this number. Example: (65-39) ÷13 = 65 ÷13-39 ÷13 = 2.
