879311 divided by 81 
We want to figure out the number of times 879311 can be divided by 81.

Moving on to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 81

On to step 2:
The number 81 fits into 87 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 6 after subtracting 81 from 87.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 81

Step 3:
The number 81 fits into 69 0 times, leaving a remainder of 69.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 69 and we're left with 69.
Append the next digit (3) from the dividend to 69 and continue with: 693 / 81

Advancing to step 4:
The number 81 fits into 693 8 times, leaving a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
If we take 648 away from 693, we end up with 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 81

Advancing to step 5:
81 can be fit into 451 5 times, resulting in a remainder of 46.
Record the quotient 5 as the next digit in the result. 
Result so far: 1085.0
Subtract 405 from 451 to get 46.
Grab the next digit (1) from the dividend, add it to 46, then carry on: 461 / 81

Let's proceed to step 6:
If we divide 461 by 81, we get 5 and a remainder of 56.
The next digit of our result is 5. 
Result so far: 10855.0
The remainder is 56 after subtracting 405 from 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
The number 81 fits into 560 6 times, leaving a remainder of 74.
Put 6 as the next digit of the answer. 
Result so far: 10855.6
If we subtract 486 from 560, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
If we divide 740 by 81, we get 9 and a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 10855.69
If we subtract 729 from 740, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
110 divided by 81 is 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 10855.691
The remainder is 29 after subtracting 81 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
When dividing 290 by 81, we get 3 with a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 10855.6913
Deduct 243 from 290 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 11:
81 can be fit into 470 5 times, resulting in a remainder of 65.
The next digit of our result is 5. 
Result so far: 10855.69135
Deduct 405 from 470 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 12:
81 goes into 650 8 times with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 10855.691358
Deduct 648 from 650 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
20 divided by 81 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 10855.691358
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 14:
The number 81 fits into 200 2 times, leaving a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 10855.69135802
If we subtract 162 from 200, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 10855.69135802, and the remainder is 3.8e-08.
