We look at the division of 51756138 by 269 
We want to figure out the number of times 51756138 can be divided by 269.

Advancing to step 1:
The number 269 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 269

Advancing to step 2:
269 goes into 51 0 times with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 269

Going ahead to step 3:
269 goes into 517 1 times with a remainder of 248.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 269 from 517 leaves us with 248.
Fetch the next digit (5) from the dividend, attach it to 248 and continue: 2485 / 269

Advancing to step 4:
2485 divided by 269 is 9 with a remainder of 64.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 2421 from 2485 leaves us with 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 269

Advancing to step 5:
The number 269 fits into 646 2 times, leaving a remainder of 108.
The number 2 becomes the next digit in our result. 
Result so far: 192.0
Subtracting 538 from 646 leaves us with 108.
Include the next digit (1) from the dividend after 108, then repeat: 1081 / 269

On to step 6:
The number 269 fits into 1081 4 times, leaving a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 1924.0
The remainder is 5 after subtracting 1076 from 1081.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 269

On to step 7:
The number 269 fits into 53 0 times, leaving a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 19240.0
If we subtract 0 from 53, we get 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 269

Going ahead to step 8:
The number 269 fits into 538 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 192402.0
If we take 538 away from 538, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 269, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 192402.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
269 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 192402.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 192402.0, with a leftover of 0.0.
