The calculation of division is divided into integer division, decimal division and fractional division. The calculation method is as follows:

I. Integers

(1) from the high order of dividend;

(2) How many digits is the divisor? Look at the first few digits of the divisor first. If it's not enough, look at one more digit.

(3) In addition to which one, which one to write the business on;

(4) The remainder of each division must be less than the divisor;

(5) If the quotient of 1 is not enough in dividend after finding the highest bit of quotient, write 0 on it;

Second, decimals

(1) When the divisor is an integer, it is calculated by integer division, and the 4 th and 4 th points of the quotient are aligned with the decimal point of the dividend;

(2) When the divisor is a decimal, it is first converted into fractional division with the divisor as an integer, and then calculated according to the divisor as an integer;

Third, the score.

The number A divided by the number B (except 0) is equal to the reciprocal of the number A multiplied by the number B.

Extended data

The meaning of division:

1, learn division, understand division, understand that division is the inverse operation of multiplication, and use division flexibly, which will be applied in practice. Facilitate the settlement of consumption and daily expenses in ordinary life.

2. Summarize the relationships between the parts of the multiplication and division method in learning, and use these relationships to check the multiplication and division method. Division is the basis of advanced operation in the future, and mathematics can be used in physics, chemistry and mathematics.
