We're dividing 660125 by 51 
We're looking to find how many times 51 goes into 660125.

Moving on to step 1:
6 divided by 51 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 51

Going ahead to step 2:
51 goes into 66 1 times with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 51 from 66 and we're left with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 51

Moving on to step 3:
150 divided by 51 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 102 from 150 to get 48.
Grab the next digit (1) from the dividend, add it to 48, then carry on: 481 / 51

Step 4:
51 can be fit into 481 9 times, resulting in a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 129.0
The remainder is 22 after subtracting 459 from 481.
Take the next digit (2) from the dividend and append it to 22, then repeat: 222 / 51

Going ahead to step 5:
When dividing 222 by 51, we get 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 1294.0
If we take 204 away from 222, we end up with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 51

Advancing to step 6:
When dividing 185 by 51, we get 3 with a remainder of 32.
The next digit of our result is 3. 
Result so far: 12943.0
Deduct 153 from 185 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
51 goes into 320 6 times with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 12943.6
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
If we divide 140 by 51, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 12943.62
Deduct 102 from 140 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 9:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 12943.627
Subtract 357 from 380 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
When dividing 230 by 51, we get 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 12943.6274
Subtract 204 from 230 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 11:
51 goes into 260 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 12943.62745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 12:
50 divided by 51 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 12943.62745
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 13:
51 can be fit into 500 9 times, resulting in a remainder of 41.
The next digit of our result is 9. 
Result so far: 12943.6274509
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 14:
The number 51 fits into 410 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 12943.62745098
Subtract 408 from 410 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 12943.62745098 with a balance of 2e-09.
