We look at the division of 66102 by 54 
Let's see how many times 54 fits into 66102.

Going ahead to step 1:
54 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 54

Moving on to step 2:
The number 54 fits into 66 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 54 from 66 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 54

Moving on to step 3:
54 goes into 121 2 times with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 108 from 121 and we're left with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 54

Let's proceed to step 4:
When dividing 130 by 54, we get 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
The remainder is 22 after subtracting 108 from 130.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 54

Let's proceed to step 5:
222 divided by 54 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 1224.0
Subtracting 216 from 222 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 6:
60 divided by 54 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1224.1
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
54 can be fit into 60 1 times, resulting in a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1224.11
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 1224.11 with a remaining 0.006.
