We divide 863299 by 81
Let's see how many times 81 fits into 863299.

Step 1:
If we divide 8 by 81, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 81

On to step 2:
81 can be fit into 86 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 81 from 86 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 81

On to step 3:
81 can be fit into 53 0 times, resulting in a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (2) from the dividend, attach it to 53 and continue: 532 / 81

Going ahead to step 4:
If we divide 532 by 81, we get 6 and a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we subtract 486 from 532, we get 46.
Append the next digit (9) from the dividend to 46 and continue with: 469 / 81

On to step 5:
When dividing 469 by 81, we get 5 with a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 1065.0
Subtract 405 from 469 to get 64.
Include the next digit (9) from the dividend after 64, then repeat: 649 / 81

Going ahead to step 6:
81 can be fit into 649 8 times, resulting in a remainder of 1.
The next digit of our result is 8. 
Result so far: 10658.0
The remainder is 1 after subtracting 648 from 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 81 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 10658.0
Subtract 0 from 10 to get 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 8:
If we divide 100 by 81, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 10658.01
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
81 can be fit into 190 2 times, resulting in a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 10658.012
Subtracting 162 from 190 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
81 goes into 280 3 times with a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 10658.0123
The remainder is 37 after subtracting 243 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
If we divide 370 by 81, we get 4 and a remainder of 46.
The number 4 becomes the next digit in our result. 
Result so far: 10658.01234
Subtracting 324 from 370 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.

Step 12:
460 divided by 81 is 5 with a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 10658.012345
The remainder is 55 after subtracting 405 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
550 divided by 81 is 6 with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 10658.0123456
The remainder is 64 after subtracting 486 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
81 goes into 640 7 times with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 10658.01234567
Subtract 567 from 640 to 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.

In conclusion, the division gives 10658.01234567 with a balance of 7.3e-08.
