We divide 660674 by 51
We want to figure out the number of times 660674 can be divided by 51.

Moving on to step 1:
51 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 51

On to step 2:
66 divided by 51 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 51 away from 66, we end up with 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 51

Step 3:
51 goes into 150 2 times with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 102 from 150 leaves us with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 51

Advancing to step 4:
51 can be fit into 486 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 129.0
Deduct 459 from 486 and we're left with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 51

Moving on to step 5:
277 divided by 51 is 5 with a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 1295.0
Subtracting 255 from 277 leaves us with 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 51

Moving on to step 6:
224 divided by 51 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 12954.0
If we take 204 away from 224, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
51 goes into 200 3 times with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 12954.3
If we take 153 away from 200, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 8:
51 goes into 470 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 12954.39
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
51 can be fit into 110 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 12954.392
Subtract 102 from 110 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
80 divided by 51 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 12954.3921
If we subtract 51 from 80, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
When dividing 290 by 51, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 12954.39215
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
51 goes into 350 6 times with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 12954.392156
If we subtract 306 from 350, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
440 divided by 51 is 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 12954.3921568
Subtract 408 from 440 to get 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 14:
320 divided by 51 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 12954.39215686
Deduct 306 from 320 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 12954.39215686, with a leftover of 1.4e-08.
