Decimal division of mathematics in the fifth grade of primary school
The fractional division in the first volume of mathematics in the fifth grade of primary school mainly involves the following knowledge points:

1, divisor is the fractional division of an integer.

When calculating, the decimal point of quotient should be aligned with the decimal point of dividend. For example, Wang Peng insists on doing morning exercises. He plans to run 22.4 kilometers in four weeks. How many kilometers does he run on average every week? " , you can align the decimal point before calculating.

2, in addition to the end of the dividend, there is a fractional division of the remainder.

Pay attention to the remainder and add 0 to continue the division. For example, "Grandpa Wang Peng plans to jog for 28km 16 days. How many kilometers does he run on average every day? " When calculating, the dividend 28 should be regarded as 28.0, and the remainder should be added with 0 to continue the division.

3. The integer part of dividend is not enough to divide quotient 1.

If the integer part of the decimal is not divided enough, the quotient 0 occupies a position in the unit of the quotient, align the decimal point of the dividend, click the decimal point of the quotient, and then continue to divide. For example, "Wang Peng plans to run 5.6km kilometers per week, and how many kilometers does it run on average every day?" When calculating, you need to regard the dividend 5.6 as 56, occupy the quotient 0 in the unit of quotient, and then calculate.
