375
Move the decimal point of both the divisor and the dividend 3 places to the right.
Set the decimal place and divide.
Thus, 1.0773 ÷ 0.513 = 2.1.
Checking by multiplying 2.1 and 0.513 will convince us that we have obtained the correct result.
(Try it.)
Example 6.48
12 ÷ 0.00032
0.00032)12.00000
The divisor has 5 decimal places.
Move the decimal point of both the divisor and the dividend 5 places to the right. We will need
to add 5 zeros to 12.
Set the decimal place and divide.
This is now the same as the division of whole numbers.
