We look at the division of 727839 by 51 
We want to figure out the number of times 727839 can be divided by 51.

On to step 1:
If we divide 7 by 51, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 51

Advancing to step 2:
51 can be fit into 72 1 times, resulting in a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
If we take 51 away from 72, we end up with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 51

Going ahead to step 3:
51 goes into 217 4 times with a remainder of 13.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 13 after subtracting 204 from 217.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 51

Moving on to step 4:
When dividing 138 by 51, we get 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 142.0
The remainder is 36 after subtracting 102 from 138.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 51

Let's proceed to step 5:
363 divided by 51 is 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 1427.0
If we subtract 357 from 363, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 51

Going ahead to step 6:
When dividing 69 by 51, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 14271.0
If we subtract 51 from 69, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
51 goes into 180 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 14271.3
Deduct 153 from 180 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 8:
The number 51 fits into 270 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 14271.35
The remainder is 15 after subtracting 255 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
The number 51 fits into 150 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 14271.352
If we subtract 102 from 150, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
The number 51 fits into 480 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 14271.3529
Deduct 459 from 480 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 11:
51 can be fit into 210 4 times, resulting in a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 14271.35294
Subtracting 204 from 210 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 12:
60 divided by 51 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 14271.352941
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
If we divide 90 by 51, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 14271.3529411
Deduct 51 from 90 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 14271.3529411 with a remaining 3.9e-07.
