We look at the division of 517932 by 51 
Let's see how many times 51 fits into 517932.

Advancing to step 1:
When dividing 5 by 51, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 51

On to step 2:
51 can be fit into 51 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 51 from 51 leaves us with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 51

Advancing to step 3:
51 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 51

Advancing to step 4:
When dividing 79 by 51, we get 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we subtract 51 from 79, we get 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 51

Step 5:
When dividing 283 by 51, we get 5 with a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 1015.0
If we take 255 away from 283, we end up with 28.
Fetch the next digit (2) from the dividend, attach it to 28 and continue: 282 / 51

On to step 6:
51 goes into 282 5 times with a remainder of 27.
Put 5 as the next digit of the answer. 
Result so far: 10155.0
Subtract 255 from 282 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 7:
The number 51 fits into 270 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10155.5
If we take 255 away from 270, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
51 goes into 150 2 times with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 10155.52
If we subtract 102 from 150, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
480 divided by 51 is 9 with a remainder of 21.
The next digit of our result is 9. 
Result so far: 10155.529
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.

On to step 10:
The number 51 fits into 210 4 times, leaving a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 10155.5294
The remainder is 6 after subtracting 204 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 11:
The number 51 fits into 60 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 10155.52941
If we subtract 51 from 60, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 12:
90 divided by 51 is 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 10155.529411
Subtracting 51 from 90 leaves us with 39.
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 10155.529411 with a remaining 3.9e-06.
