We're dividing 660682 by 51 
Our goal is to divide 660682 by 51.

Advancing to step 1:
51 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 51

Going ahead to step 2:
If we divide 66 by 51, we get 1 and a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 51 from 66 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 51

Advancing to step 3:
51 goes into 150 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 12.0
Subtract 102 from 150 to get 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 51

On to step 4:
51 can be fit into 486 9 times, resulting in a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 129.0
If we subtract 459 from 486, we get 27.
Take the next digit (8) from the dividend and append it to 27, then repeat: 278 / 51

Moving on to step 5:
51 can be fit into 278 5 times, resulting in a remainder of 23.
The next digit of our result is 5. 
Result so far: 1295.0
If we take 255 away from 278, we end up with 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 51

Moving on to step 6:
If we divide 232 by 51, we get 4 and a remainder of 28.
The next digit of our result is 4. 
Result so far: 12954.0
If we subtract 204 from 232, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
51 can be fit into 280 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 12954.5
Subtracting 255 from 280 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
250 divided by 51 is 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 12954.54
If we take 204 away from 250, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 9:
460 divided by 51 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 12954.549
Subtract 459 from 460 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 10:
51 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 12954.549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 12954.54901
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 12:
If we divide 490 by 51, we get 9 and a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 12954.549019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 13:
51 can be fit into 310 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 12954.5490196
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
40 divided by 51 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 12954.5490196
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 12954.5490196, with a leftover of 4e-08.
