Let's divide 86190731 by 827
We want to divide 86190731 by 827.

Advancing to step 1:
When dividing 8 by 827, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 827

Let's proceed to step 2:
The number 827 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Take the next digit (1) from the dividend and append it to 86, then repeat: 861 / 827

Advancing to step 3:
827 goes into 861 1 times with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 827 from 861 to get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 827

Step 4:
827 goes into 349 0 times with a remainder of 349.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 349 after subtracting 0 from 349.
Grab the next digit (0) from the dividend, add it to 349, then carry on: 3490 / 827

Advancing to step 5:
3490 divided by 827 is 4 with a remainder of 182.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Subtracting 3308 from 3490 leaves us with 182.
Grab the next digit (7) from the dividend, add it to 182, then carry on: 1827 / 827

Moving on to step 6:
The number 827 fits into 1827 2 times, leaving a remainder of 173.
The next digit of our result is 2. 
Result so far: 1042.0
If we subtract 1654 from 1827, we get 173.
Take the next digit (3) from the dividend and append it to 173, then repeat: 1733 / 827

Going ahead to step 7:
1733 divided by 827 is 2 with a remainder of 79.
Write down 2 as next digit of the result. 
Result so far: 10422.0
Deduct 1654 from 1733 and we're left with 79.
Take the next digit (1) from the dividend and append it to 79, then repeat: 791 / 827

On to step 8:
If we divide 791 by 827, we get 0 and a remainder of 791.
Put 0 as the next digit of the answer. 
Result so far: 104220.0
The remainder is 791 after subtracting 0 from 791.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7910, and continue the process.

Step 9:
The number 827 fits into 7910 9 times, leaving a remainder of 467.
Put 9 as the next digit of the answer. 
Result so far: 104220.9
Subtract 7443 from 7910 to get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Going ahead to step 10:
827 can be fit into 4670 5 times, resulting in a remainder of 535.
Use 5 as the next digit of our solution. 
Result so far: 104220.95
Subtract 4135 from 4670 to get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Moving on to step 11:
827 goes into 5350 6 times with a remainder of 388.
Record the quotient 6 as the next digit in the result. 
Result so far: 104220.956
If we subtract 4962 from 5350, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 12:
The number 827 fits into 3880 4 times, leaving a remainder of 572.
Put 4 as the next digit of the answer. 
Result so far: 104220.9564
If we take 3308 away from 3880, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Going ahead to step 13:
The number 827 fits into 5720 6 times, leaving a remainder of 758.
Put 6 as the next digit of the answer. 
Result so far: 104220.95646
Deduct 4962 from 5720 and we're left with 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Going ahead to step 14:
827 goes into 7580 9 times with a remainder of 137.
Use 9 as the next digit of our solution. 
Result so far: 104220.956469
Subtract 7443 from 7580 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Going ahead to step 15:
827 goes into 1370 1 times with a remainder of 543.
The number 1 becomes the next digit in our result. 
Result so far: 104220.9564691
Subtracting 827 from 1370 leaves us with 543.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5430, and continue the process.

On to step 16:
5430 divided by 827 is 6 with a remainder of 468.
Use 6 as the next digit of our solution. 
Result so far: 104220.95646916
If we take 4962 away from 5430, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Our division results in 104220.95646916 with a remaining 4.68e-07.
