We look at the division of 816872 by 81 
We want to divide 816872 by 81.

Step 1:
If we divide 8 by 81, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 81

Going ahead to step 2:
The number 81 fits into 81 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 81 away from 81, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 81

Step 3:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 6, we get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 81

On to step 4:
The number 81 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 68 leaves us with 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 81

Advancing to step 5:
81 can be fit into 687 8 times, resulting in a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 1008.0
Deduct 648 from 687 and we're left with 39.
Take the next digit (2) from the dividend and append it to 39, then repeat: 392 / 81

Let's proceed to step 6:
The number 81 fits into 392 4 times, leaving a remainder of 68.
The next digit of our result is 4. 
Result so far: 10084.0
If we take 324 away from 392, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 7:
The number 81 fits into 680 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 10084.8
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
81 goes into 320 3 times with a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 10084.83
If we subtract 243 from 320, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 9:
If we divide 770 by 81, we get 9 and a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 10084.839
Subtracting 729 from 770 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 10:
When dividing 410 by 81, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 10084.8395
Deduct 405 from 410 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
The number 81 fits into 50 0 times, leaving a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 10084.8395
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
The number 81 fits into 500 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 10084.839506
Subtracting 486 from 500 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 13:
81 goes into 140 1 times with a remainder of 59.
Record the quotient 1 as the next digit in the result. 
Result so far: 10084.8395061
The remainder is 59 after subtracting 81 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 14:
590 divided by 81 is 7 with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 10084.83950617
If we take 567 away from 590, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

In conclusion, the division gives 10084.83950617 with a balance of 2.3e-08.
