We look at the division of 413148 by 51 
We want to divide 413148 by 51.

Step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 51

On to step 2:
41 divided by 51 is 0 with a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 41, we end up with 41.
Fetch the next digit (3) from the dividend, attach it to 41 and continue: 413 / 51

Advancing to step 3:
If we divide 413 by 51, we get 8 and a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 408 from 413 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 51

Advancing to step 4:
51 goes into 51 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 81.0
If we take 51 away from 51, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 51

Let's proceed to step 5:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 810.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 51

On to step 6:
48 divided by 51 is 0 with a remainder of 48.
The next digit of our result is 0. 
Result so far: 8100.0
Deduct 0 from 48 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 7:
If we divide 480 by 51, we get 9 and a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 8100.9
Deduct 459 from 480 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
When dividing 210 by 51, we get 4 with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 8100.94
If we subtract 204 from 210, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
60 divided by 51 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 8100.941
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
51 can be fit into 90 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 8100.9411
The remainder is 39 after subtracting 51 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 8100.9411 with a remaining 0.00039.
