We divide 663728 by 51
Let's see how many times 51 fits into 663728.

Step 1:
51 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 51

Let's proceed to step 2:
If we divide 66 by 51, we get 1 and a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 51 from 66 to get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 51

Advancing to step 3:
The number 51 fits into 153 3 times, leaving a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
If we take 153 away from 153, we end up with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 51

Let's proceed to step 4:
When dividing 7 by 51, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 130.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 51

Step 5:
If we divide 72 by 51, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 1301.0
The remainder is 21 after subtracting 51 from 72.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 51

On to step 6:
The number 51 fits into 218 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 13014.0
Subtracting 204 from 218 leaves us 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.

Advancing to step 7:
51 goes into 140 2 times with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 13014.2
The remainder is 38 after subtracting 102 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
51 can be fit into 380 7 times, resulting in a remainder of 23.
The next digit of our result is 7. 
Result so far: 13014.27
The remainder is 23 after subtracting 357 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
51 can be fit into 230 4 times, resulting in a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 13014.274
The remainder is 26 after subtracting 204 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 10:
The number 51 fits into 260 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 13014.2745
If we subtract 255 from 260, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
51 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 13014.2745
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
51 goes into 500 9 times with a remainder of 41.
The number 9 becomes the next digit in our result. 
Result so far: 13014.274509
Subtracting 459 from 500 leaves us 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 13:
If we divide 410 by 51, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 13014.2745098
If we subtract 408 from 410, we 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.

Let's proceed to step 14:
20 divided by 51 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 13014.2745098
If we take 0 away from 20, 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.

The final outcome is 13014.2745098, with a leftover of 2e-08.
