We look at the division of 168479 by 81 
Let's see how many times 81 fits into 168479.

On to step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 81

Moving on to step 2:
If we divide 16 by 81, we get 0 and a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 81

Advancing to step 3:
If we divide 168 by 81, we get 2 and a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 6 after subtracting 162 from 168.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 81

Step 4:
If we divide 64 by 81, we get 0 and a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (7) from the dividend after 64, then repeat: 647 / 81

Let's proceed to step 5:
81 can be fit into 647 7 times, resulting in a remainder of 80.
Write down 7 as next digit of the result. 
Result so far: 207.0
Subtract 567 from 647 to get 80.
Bring next digit (9) of the dividend behind the 80 and repeat the process: 809 / 81

Advancing to step 6:
When dividing 809 by 81, we get 9 with a remainder of 80.
Write down 9 as next digit of the result. 
Result so far: 2079.0
Subtracting 729 from 809 leaves us 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.

Let's proceed to step 7:
If we divide 800 by 81, we get 9 and a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 2079.9
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.

Moving on to step 8:
710 divided by 81 is 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 2079.98
If we take 648 away from 710, we end up 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.

Advancing to step 9:
620 divided by 81 is 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 2079.987
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.

On to step 10:
When dividing 530 by 81, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 2079.9876
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.

Going ahead to step 11:
When dividing 440 by 81, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 2079.98765
If we take 405 away from 440, we end up with 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 12:
350 divided by 81 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 2079.987654
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.

Step 13:
If we divide 260 by 81, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2079.9876543
If we take 243 away from 260, we end up 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.

Going ahead to step 14:
170 divided by 81 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2079.98765432
Deduct 162 from 170 and we're left 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.

The final result is 2079.98765432 with a remainder of 8e-09.
