We're dividing 876891 by 86 
We want to figure out the number of times 876891 can be divided by 86.

Going ahead to step 1:
86 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
Subtract 0 from 8 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 86

Moving on to step 2:
86 can be fit into 87 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 86 from 87, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 86

On to step 3:
When dividing 16 by 86, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 86

On to step 4:
86 can be fit into 168 1 times, resulting in a remainder of 82.
The next digit of our result is 1. 
Result so far: 101.0
Subtract 86 from 168 to get 82.
Fetch the next digit (9) from the dividend, attach it to 82 and continue: 829 / 86

Step 5:
If we divide 829 by 86, we get 9 and a remainder of 55.
The number 9 becomes the next digit in our result. 
Result so far: 1019.0
Subtracting 774 from 829 leaves us with 55.
Include the next digit (1) from the dividend after 55, then repeat: 551 / 86

Moving on to step 6:
86 can be fit into 551 6 times, resulting in a remainder of 35.
The number 6 becomes the next digit in our result. 
Result so far: 10196.0
Deduct 516 from 551 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
If we divide 350 by 86, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 10196.4
Deduct 344 from 350 and we're left 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 8:
If we divide 60 by 86, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 10196.4
Subtracting 0 from 60 leaves us 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.

Moving on to step 9:
600 divided by 86 is 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 10196.406
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 10:
86 can be fit into 840 9 times, resulting in a remainder of 66.
The next digit of our result is 9. 
Result so far: 10196.4069
The remainder is 66 after subtracting 774 from 840.
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 11:
If we divide 660 by 86, we get 7 and a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 10196.40697
Deduct 602 from 660 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 12:
The number 86 fits into 580 6 times, leaving a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 10196.406976
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
When dividing 640 by 86, we get 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 10196.4069767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
380 divided by 86 is 4 with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 10196.40697674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 10196.40697674 with a remainder of 3.6e-08.
