Let's divide 879353 by 81
We want to divide 879353 by 81.

Advancing to 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.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 81

Advancing to step 2:
When dividing 87 by 81, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 81 from 87 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 81

On to step 3:
The number 81 fits into 69 0 times, leaving a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 69 after subtracting 0 from 69.
Take the next digit (3) from the dividend and append it to 69, then repeat: 693 / 81

Advancing to step 4:
81 can be fit into 693 8 times, resulting in a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Deduct 648 from 693 and we're left with 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 81

Step 5:
When dividing 455 by 81, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 1085.0
If we take 405 away from 455, we end up with 50.
Grab the next digit (3) from the dividend, add it to 50, then carry on: 503 / 81

Advancing to step 6:
81 can be fit into 503 6 times, resulting in a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 10856.0
The remainder is 17 after subtracting 486 from 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
81 goes into 170 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 10856.2
Subtracting 162 from 170 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.

Going ahead to step 8:
When dividing 80 by 81, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10856.2
Deduct 0 from 80 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 9:
If we divide 800 by 81, we get 9 and a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 10856.209
Deduct 729 from 800 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 10:
The number 81 fits into 710 8 times, leaving a remainder of 62.
The next digit of our result is 8. 
Result so far: 10856.2098
Subtract 648 from 710 to 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.

Let's proceed to step 11:
620 divided by 81 is 7 with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 10856.20987
Subtract 567 from 620 to 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.

On to step 12:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 10856.209876
If we subtract 486 from 530, we 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.

Advancing to step 13:
If we divide 440 by 81, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 10856.2098765
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.

Advancing to step 14:
81 goes into 350 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 10856.20987654
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 10856.20987654 with a balance of 2.6e-08.
