Let's divide 86937020 by 815
We want to figure out the number of times 86937020 can be divided by 815.

Advancing to step 1:
815 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 815

On to step 2:
815 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 815

Going ahead to step 3:
If we divide 869 by 815, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 54 after subtracting 815 from 869.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 815

Advancing to step 4:
The number 815 fits into 543 0 times, leaving a remainder of 543.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 543 after subtracting 0 from 543.
Bring next digit (7) of the dividend behind the 543 and repeat the process: 5437 / 815

On to step 5:
If we divide 5437 by 815, we get 6 and a remainder of 547.
The next digit of our result is 6. 
Result so far: 106.0
If we subtract 4890 from 5437, we get 547.
Fetch the next digit (0) from the dividend, attach it to 547 and continue: 5470 / 815

Moving on to step 6:
When dividing 5470 by 815, we get 6 with a remainder of 580.
Use 6 as the next digit of our solution. 
Result so far: 1066.0
The remainder is 580 after subtracting 4890 from 5470.
Take the next digit (2) from the dividend and append it to 580, then repeat: 5802 / 815

Going ahead to step 7:
815 can be fit into 5802 7 times, resulting in a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 10667.0
Subtracting 5705 from 5802 leaves us with 97.
Include the next digit (0) from the dividend after 97, then repeat: 970 / 815

Step 8:
815 can be fit into 970 1 times, resulting in a remainder of 155.
Write down 1 as next digit of the result. 
Result so far: 106671.0
If we take 815 away from 970, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

On to step 9:
1550 divided by 815 is 1 with a remainder of 735.
The number 1 becomes the next digit in our result. 
Result so far: 106671.1
If we take 815 away from 1550, we end up with 735.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7350, and continue the process.

Step 10:
If we divide 7350 by 815, we get 9 and a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 106671.19
Subtract 7335 from 7350 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
If we divide 150 by 815, we get 0 and a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 106671.19
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 12:
815 goes into 1500 1 times with a remainder of 685.
Put 1 as the next digit of the answer. 
Result so far: 106671.1901
The remainder is 685 after subtracting 815 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 13:
815 goes into 6850 8 times with a remainder of 330.
The number 8 becomes the next digit in our result. 
Result so far: 106671.19018
Deduct 6520 from 6850 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Going ahead to step 14:
When dividing 3300 by 815, we get 4 with a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 106671.190184
Subtracting 3260 from 3300 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 15:
815 goes into 400 0 times with a remainder of 400.
The next digit of our result is 0. 
Result so far: 106671.190184
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 16:
If we divide 4000 by 815, we get 4 and a remainder of 740.
Write down 4 as next digit of the result. 
Result so far: 106671.19018404
The remainder is 740 after subtracting 3260 from 4000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

The final result is 106671.19018404 with a remainder of 7.4e-07.
