0. 12÷0.25=0.48

Analysis: In the vertical calculation of division, the divisor is a decimal, and it must be turned into an integer first. 0.25 expansion 100 times becomes 25, and dividends are also expanded 100 times becomes 12. Then calculate by integer division.

A divider is the division of two digits. Look at the top two dividends first. 12 is less than 25. If it is not enough to divide, it is necessary to add 0 as the complement and write the quotient digit as 0. Then use 120÷25=4 and 20; Quotient 4 is written in the tenth place. The remainder 20 continues to add 0,200 ÷ 25 = 8, and the quotient 8 is written on the percentile. It is 0. 12÷0.25, and the final quotient is 0.48.

Extended data:

Divider is a decimal division rule:?

1, first look at how many decimal places the divisor has, then move the decimal point of the divisor to the right by several places, and make up the digits with zero;

2. Divide dividends from high positions. How many factors are there? Look at the first few figures of dividends. If it's not enough, watch another one.

3. Write the quotient on the divisor. If the divisor is not enough, put the quotient 0 on this.

4. The remainder of each division must be less than the divisor. Place the digits of the divisor on the right of the remainder and continue the division.
