We look at the division of 879983 by 81 
Let's see how many times 81 fits into 879983.

Let's proceed to step 1:
81 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 81

Moving on to step 2:
81 goes into 87 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 81 from 87, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 81

Step 3:
The number 81 fits into 69 0 times, leaving a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 69 leaves us with 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 81

On to step 4:
When dividing 699 by 81, we get 8 with a remainder of 51.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
The remainder is 51 after subtracting 648 from 699.
Include the next digit (8) from the dividend after 51, then repeat: 518 / 81

Advancing to step 5:
81 can be fit into 518 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1086.0
The remainder is 32 after subtracting 486 from 518.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 81

On to step 6:
When dividing 323 by 81, we get 3 with a remainder of 80.
Write down 3 as next digit of the result. 
Result so far: 10863.0
Deduct 243 from 323 and we're left 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.

Advancing to step 7:
When dividing 800 by 81, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 10863.9
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 8:
The number 81 fits into 710 8 times, leaving a remainder of 62.
The next digit of our result is 8. 
Result so far: 10863.98
If we subtract 648 from 710, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
81 can be fit into 620 7 times, resulting in a remainder of 53.
The next digit of our result is 7. 
Result so far: 10863.987
If we subtract 567 from 620, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 10:
When dividing 530 by 81, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 10863.9876
Subtract 486 from 530 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 11:
When dividing 440 by 81, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 10863.98765
Subtract 405 from 440 to get 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 12:
81 can be fit into 350 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 10863.987654
If we subtract 324 from 350, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
When dividing 260 by 81, we get 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 10863.9876543
Subtract 243 from 260 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 14:
170 divided by 81 is 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 10863.98765432
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 10863.98765432 with a balance of 8e-09.
