We look at the division of 639726 by 50 
Let's see how many times 50 fits into 639726.

Let's proceed to step 1:
50 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 50

On to step 2:
The number 50 fits into 63 1 times, leaving a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 50 from 63 to get 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 50

Moving on to step 3:
The number 50 fits into 139 2 times, leaving a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 100 from 139 to get 39.
Fetch the next digit (7) from the dividend, attach it to 39 and continue: 397 / 50

Going ahead to step 4:
50 can be fit into 397 7 times, resulting in a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
Subtract 350 from 397 to get 47.
Grab the next digit (2) from the dividend, add it to 47, then carry on: 472 / 50

Advancing to step 5:
The number 50 fits into 472 9 times, leaving a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 1279.0
Subtracting 450 from 472 leaves us with 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 50

Advancing to step 6:
226 divided by 50 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 12794.0
Subtracting 200 from 226 leaves us with 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 7:
50 can be fit into 260 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 12794.5
Subtract 250 from 260 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 50, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12794.52
Subtract 100 from 100 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.

Advancing to step 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12794.52
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:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 12794.52
If we take 0 away from 0, 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.

Our division results in 12794.52 with a remaining 0.0.
