The vertical division algorithm starts with the most significant divisor. If there are several divisors, look at the first few digits of the dividend. If the division is not enough, look at one more digit.
A divisor is the division of decimals of integers.
The divider is a fractional division of an integer, which can be calculated according to the following steps:
1, first removed according to the law of integer division;
2. The decimal point of quotient should be aligned with the decimal point of dividend;
3. When there is a remainder at the end of the dividend, add 0 after the remainder (the 0 here should be added below the next result bit of the quotient), and then continue the division.
Second, divisor is a fractional division of decimals.
The divider is a fractional division of decimals, which can be calculated according to the following steps:
1, first remove the decimal point of the divisor to make it an integer;
Here, we only need to convert the divisor into an integer, and of course, the dividend should be changed accordingly. For example, if you divide 5.63 by 7.8, you only need to convert it into 56.3 divided by 78.
2. The conversion process will lead to corresponding changes in the remainder, but the quotient remains unchanged.
Third, matters needing attention
1, when the column is vertical, the unit of quotient should be aligned with the unit of dividend. The decimal point of quotient should actually be exactly the same as the decimal point of dividend, but sometimes the result is an integer, so the decimal point is not used. )
2. The product of quotient and divisor is written under the dividend.
Finally, draw a horizontal line under the product.
4. Write the difference between the dividend and the product of quotient and divisor under the horizontal line.
