Find difference of 327.243 and 652.5 
Solution: Subtraction proceeds in the following steps:
Step 1: Convert Unlike Decimal to like decimal
Decimal 327.243 and 652.5 are Unlike Decimals, because:
327.243 have three decimal places i.e. digit 2, 4 and 3
652.5 have only one decimal place i.e. digit 5
Now, 652.5 can be converted into a decimal having two decimal places i.e. by adding 0(Zero) at its hundredths and thousandths place.
And after conversion we get;
652.500 having two decimal places i.e. digit 5, 0 and 0
Now, 327.243 and 652.500 are like Decimals because both have similar decimal places
Step 2: Write minuend and subtrahend in such a way that decimal point and digit of same place values should be at same vertical order or same place value
652.500
 327.243
Step 3: Do the subtraction as in case of whole numbers and we get:
Subtraction of Digits at thousandths place and we get:
0  3 = ???
Here we can see that 0 is less than 3, so we will carry 1 from tenths digit (because digit at hundredths place is also 0) and we get;
Digit 9 at hundredths place and digit 10 at thousand place (as shown above), so the subtraction will be:
10  3 = 7
7 is written in the result at same place value.
Subtraction of Digits at hundredths place and we get:
Now digit at hundredths place is 9 (as shown above) and its subtraction will be:
9  4 = 5
5 is written in the result at same place value.
Subtraction of Digits at tenths place.
Now digit at tenths place is 4 (as shown above) and its subtraction will be:
4  2 = 2
2 is written in the result at same place value.
Subtraction of Digits at ones place
2  7 = ???
Here we can see that 2 is less than 7, so we will carry 1 from tens digit and we get digit 12 at ones place (as shown above), so the subtraction will be:
12  7 = 5
5 is written in the result at same place value.
Subtraction of Digits at tens place.
Now digit at tens place is 4 (as shown above) and its subtraction will be:
4  2 = 2
2 is written in the result at same place value.
Subtraction of Digits at hundreds place.
6  3 = 3
3 is written in the result at same place value.
Step 4: Decimal Point of given decimals and answer should be at same vertical order or at same place.
