We look at the division of 8515921 by 727 
We're looking to find how many times 727 goes into 8515921.

Let's proceed to step 1:
When dividing 8 by 727, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 727

Let's proceed to step 2:
The number 727 fits into 85 0 times, leaving a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 727

Moving on to step 3:
If we divide 851 by 727, we get 1 and a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 124 after subtracting 727 from 851.
Fetch the next digit (5) from the dividend, attach it to 124 and continue: 1245 / 727

Moving on to step 4:
1245 divided by 727 is 1 with a remainder of 518.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtracting 727 from 1245 leaves us with 518.
Append the next digit (9) from the dividend to 518 and continue with: 5189 / 727

On to step 5:
When dividing 5189 by 727, we get 7 with a remainder of 100.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
Deduct 5089 from 5189 and we're left with 100.
Grab the next digit (2) from the dividend, add it to 100, then carry on: 1002 / 727

Advancing to step 6:
1002 divided by 727 is 1 with a remainder of 275.
Put 1 as the next digit of the answer. 
Result so far: 1171.0
The remainder is 275 after subtracting 727 from 1002.
Bring next digit (1) of the dividend behind the 275 and repeat the process: 2751 / 727

Advancing to step 7:
When dividing 2751 by 727, we get 3 with a remainder of 570.
Record the quotient 3 as the next digit in the result. 
Result so far: 11713.0
Subtracting 2181 from 2751 leaves us with 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Moving on to step 8:
When dividing 5700 by 727, we get 7 with a remainder of 611.
Use 7 as the next digit of our solution. 
Result so far: 11713.7
Deduct 5089 from 5700 and we're left with 611.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6110, and continue the process.

Going ahead to step 9:
6110 divided by 727 is 8 with a remainder of 294.
Put 8 as the next digit of the answer. 
Result so far: 11713.78
Subtract 5816 from 6110 to get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Moving on to step 10:
727 can be fit into 2940 4 times, resulting in a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 11713.784
If we take 2908 away from 2940, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 11:
If we divide 320 by 727, we get 0 and a remainder of 320.
Record the quotient 0 as the next digit in the result. 
Result so far: 11713.784
The remainder is 320 after subtracting 0 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
727 goes into 3200 4 times with a remainder of 292.
The number 4 becomes the next digit in our result. 
Result so far: 11713.78404
The remainder is 292 after subtracting 2908 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 13:
The number 727 fits into 2920 4 times, leaving a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 11713.784044
Subtracting 2908 from 2920 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 11713.784044 with a remaining 1.2e-06.
