We look at the division of 872486 by 83 
We want to figure out the number of times 872486 can be divided by 83.

Step 1:
83 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 83

Let's proceed to step 2:
If we divide 87 by 83, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 4 after subtracting 83 from 87.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 83

Going ahead to step 3:
83 goes into 42 0 times with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 42, we get 42.
Include the next digit (4) from the dividend after 42, then repeat: 424 / 83

Step 4:
83 goes into 424 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtract 415 from 424 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 83

On to step 5:
98 divided by 83 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1051.0
Subtract 83 from 98 to get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 83

Advancing to step 6:
When dividing 156 by 83, we get 1 with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 10511.0
If we subtract 83 from 156, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Going ahead to step 7:
When dividing 730 by 83, we get 8 with a remainder of 66.
Use 8 as the next digit of our solution. 
Result so far: 10511.8
If we take 664 away from 730, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
83 can be fit into 660 7 times, resulting in a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 10511.87
Subtract 581 from 660 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 9:
83 can be fit into 790 9 times, resulting in a remainder of 43.
Write down 9 as next digit of the result. 
Result so far: 10511.879
The remainder is 43 after subtracting 747 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
83 goes into 430 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 10511.8795
If we take 415 away from 430, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 11:
83 goes into 150 1 times with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 10511.87951
The remainder is 67 after subtracting 83 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 12:
The number 83 fits into 670 8 times, leaving a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 10511.879518
Subtracting 664 from 670 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 13:
If we divide 60 by 83, we get 0 and a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 10511.879518
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 14:
83 goes into 600 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 10511.87951807
The remainder is 19 after subtracting 581 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 10511.87951807 with a remainder of 1.9e-08.
