We look at the division of 84879 by 81 
We want to figure out the number of times 84879 can be divided by 81.

Going ahead 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.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 81

On to step 2:
When dividing 84 by 81, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 81 from 84, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 81

On to step 3:
The number 81 fits into 38 0 times, leaving a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 38 leaves us with 38.
Grab the next digit (7) from the dividend, add it to 38, then carry on: 387 / 81

Going ahead to step 4:
81 can be fit into 387 4 times, resulting in a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
If we subtract 324 from 387, we get 63.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 81

Moving on to step 5:
639 divided by 81 is 7 with a remainder of 72.
The next digit of our result is 7. 
Result so far: 1047.0
Subtracting 567 from 639 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 6:
720 divided by 81 is 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 1047.8
If we subtract 648 from 720, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
720 divided by 81 is 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 1047.88
Subtract 648 from 720 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 1047.88 with a remainder of 0.072.
