The divisor is a division of decimals, so you need to move the decimal point of the divisor to the right first to make it an integer. Then, the dividend and divisor are multiplied by the same number (10 or 100, etc. ) At the same time, make the divisor an integer.

Divider is the division of decimals, so you need to convert both divisor and dividend into integers first. In order to achieve this goal, we need to move the decimal points of dividend and divisor to the right by the same number of digits, so that the decimal part disappears and becomes integer division. If the decimal point of the divisor is moved by n bits to the right, then the decimal point of the dividend should also be moved by n bits to the right. This is because in fractional division, the multiple relationship between dividend and divisor is reflected by the position of decimal point.

When we move the decimal point to the right, we actually multiply the original value by a specific number. For example, moving the decimal point one place to the right is to multiply the original value by 10. So when we move the decimal point, the final result may have an impact. In mathematics, when two numbers are divided, if the units of divisor and dividend are different, we need to unify the units of dividend and divisor, so that they have the same unit, and then divide.

Division algorithm:

1, law of division: In the division operation, we can divide the divisor into the form of multiplication of two numbers, and then divide the dividend and these two numbers respectively and multiply them again, and the result is the same as that of dividing the dividend directly by the divisor. This rule can be expressed as (a÷b)÷c=a÷(b×c).

2. Division commutative law: In division operation, we can exchange the positions of dividend and divisor before division, and the result is the same as that obtained by direct division. This law can be expressed as a ÷ b = b ÷ a

3. Law of Division and Distribution: In the division operation, we can decompose the dividend into the form of adding multiple numbers, and then divide each summand by the sum of the corresponding divisors, and the result is the same as the direct division of the dividend by the divisor. This rule can be expressed as (a+b+c)÷d=(a÷d)+(b÷d)+(c÷d).

4. The supplementary law of division: When the dividend cannot be divisible by the dividend, the quotient and remainder divided by the dividend are equal to the dividend. This law can be expressed as a÷b=c…r, where a is the dividend, b is the divisor, c is the quotient, and r is the remainder.
