We're dividing 104579 by 81 
Let's see how many times 81 fits into 104579.

Advancing to step 1:
1 divided by 81 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 81

On to step 2:
81 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 81

Advancing to step 3:
If we divide 104 by 81, we get 1 and a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 81 from 104, we get 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 81

On to step 4:
81 goes into 235 2 times with a remainder of 73.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 162 from 235 and we're left with 73.
Bring next digit (7) of the dividend behind the 73 and repeat the process: 737 / 81

Advancing to step 5:
81 can be fit into 737 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
The remainder is 8 after subtracting 729 from 737.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 81

Moving on to step 6:
When dividing 89 by 81, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1291.0
Subtract 81 from 89 to 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.

On to step 7:
81 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 1291.0
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 8:
When dividing 800 by 81, we get 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 1291.09
If we take 729 away from 800, we end up 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.

On to step 9:
81 can be fit into 710 8 times, resulting in a remainder of 62.
The next digit of our result is 8. 
Result so far: 1291.098
Deduct 648 from 710 and we're left with 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 10:
The number 81 fits into 620 7 times, leaving a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 1291.0987
Deduct 567 from 620 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 11:
If we divide 530 by 81, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 1291.09876
Subtracting 486 from 530 leaves us with 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 12:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1291.098765
If we subtract 405 from 440, we 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.

Moving on to step 13:
The number 81 fits into 350 4 times, leaving a remainder of 26.
The next digit of our result is 4. 
Result so far: 1291.0987654
Subtracting 324 from 350 leaves us 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.

Going ahead to step 14:
81 can be fit into 260 3 times, resulting in a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 1291.09876543
Deduct 243 from 260 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 1291.09876543 and a remainder of 1.7e-08.
