We look at the division of 872630 by 86 
We want to divide 872630 by 86.

Going ahead to step 1:
The number 86 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 86

On to step 2:
86 can be fit into 87 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 86 from 87 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 86

Advancing to step 3:
The number 86 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 12, we get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 86

Advancing to step 4:
86 can be fit into 126 1 times, resulting in a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we subtract 86 from 126, we get 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 86

Advancing to step 5:
If we divide 403 by 86, we get 4 and a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 1014.0
Subtracting 344 from 403 leaves us with 59.
Append the next digit (0) from the dividend to 59 and continue with: 590 / 86

Going ahead to step 6:
If we divide 590 by 86, we get 6 and a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 10146.0
If we take 516 away from 590, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
The number 86 fits into 740 8 times, leaving a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 10146.8
Subtracting 688 from 740 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
When dividing 520 by 86, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 10146.86
If we take 516 away from 520, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
86 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 10146.86
Subtracting 0 from 40 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.

Going ahead to step 10:
If we divide 400 by 86, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 10146.8604
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
If we divide 560 by 86, we get 6 and a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 10146.86046
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
When dividing 440 by 86, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 10146.860465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
If we divide 100 by 86, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 10146.8604651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
140 divided by 86 is 1 with a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 10146.86046511
Subtract 86 from 140 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 10146.86046511, and the remainder is 5.4e-08.
