Let's divide 863891 by 82
We're looking to find how many times 82 goes into 863891.

Step 1:
8 divided by 82 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 82

Let's proceed to step 2:
The number 82 fits into 86 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 82 from 86 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 82

On to step 3:
If we divide 43 by 82, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 43, we end up with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 82

On to step 4:
The number 82 fits into 438 5 times, leaving a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
Subtracting 410 from 438 leaves us with 28.
Grab the next digit (9) from the dividend, add it to 28, then carry on: 289 / 82

Let's proceed to step 5:
289 divided by 82 is 3 with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 1053.0
Subtract 246 from 289 to get 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 82

On to step 6:
82 can be fit into 431 5 times, resulting in a remainder of 21.
Record the quotient 5 as the next digit in the result. 
Result so far: 10535.0
Subtract 410 from 431 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
82 can be fit into 210 2 times, resulting in a remainder of 46.
The next digit of our result is 2. 
Result so far: 10535.2
Subtracting 164 from 210 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 8:
82 can be fit into 460 5 times, resulting in a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 10535.25
Deduct 410 from 460 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
82 can be fit into 500 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 10535.256
Subtracting 492 from 500 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
82 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 10535.256
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
If we divide 800 by 82, we get 9 and a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 10535.25609
Deduct 738 from 800 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 12:
620 divided by 82 is 7 with a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 10535.256097
Deduct 574 from 620 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 13:
82 goes into 460 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 10535.2560975
If we take 410 away from 460, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
82 goes into 500 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 10535.25609756
Subtracting 492 from 500 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 10535.25609756 with a remainder of 8e-09.
