1, different meanings: division refers to how many times one number is another. In addition to getting rid of; Removing means not counting, but dividing.

2, the writing is different: division is A divided by B, A is dividend, B is divisor, written as A/B, except A divided by B, A is divisor, B is dividend, written as B/A.

2. The order is different: the divisor is divided by the dividend. When there is a divisor, the first number before the divisor is the divisor, and the number after it is the dividend. Divide is the dividend divided by the divisor, and the divisor divided by the dividend and then divided by the divisor.

The origin of division can be traced back to ancient times, and it can be traced back to Oracle Bone Inscriptions in Shang Dynasty. People in Shang Dynasty began to use division to calculate. Since then, the division operation has gradually formed a modern division operation in the continuous evolution and development. In ancient China, people mastered the division of numbers very early. The earliest use was in the pre-Qin period, or earlier.

Since the Spring and Autumn Period before the Warring States Period in BC, after multiplication with the "99" table appeared in China, people also summed up the method of calculating division with formulas. At that time, division was mainly calculated by calculation and formula in China. Division is a basic mathematical operation, which has different forms in different fields.

According to the meaning of division, division is the operation of finding the other factor by knowing the product of two factors and one of them. According to the reciprocal relationship between division and multiplication, if the divisor is 0;

Then: when the dividend is not 0 (for example, 3÷0), because "any number multiplied by 0 is equal to 0, but it cannot be equal to a number that is not 0 (for example, 3)", the quotient of the division formula does not exist at this time-that is, 0 times of any number cannot be a non-zero number;

When the dividend is 0, that is, the division formula is 0÷0, because "any number multiplied by 0 equals 0", the quotient can be any number-that is, 0 times of any number equals 0. In order to avoid the above two situations, it is mathematically stipulated that "0 cannot be divided".
