We're dividing 854057 by 81 
We want to divide 854057 by 81.

On to step 1:
If we divide 8 by 81, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 81

Let's proceed to step 2:
85 divided by 81 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 4 after subtracting 81 from 85.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 81

On to step 3:
The number 81 fits into 44 0 times, leaving a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 44 to get 44.
Include the next digit (0) from the dividend after 44, then repeat: 440 / 81

Moving on to step 4:
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: 105.0
If we subtract 405 from 440, we get 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 81

Step 5:
If we divide 355 by 81, we get 4 and a remainder of 31.
The next digit of our result is 4. 
Result so far: 1054.0
If we take 324 away from 355, we end up with 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 81

Moving on to step 6:
When dividing 317 by 81, we get 3 with a remainder of 74.
Record the quotient 3 as the next digit in the result. 
Result so far: 10543.0
If we subtract 243 from 317, 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.

Going ahead to step 7:
740 divided by 81 is 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 10543.9
Subtracting 729 from 740 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 8:
81 goes into 110 1 times with a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 10543.91
Subtracting 81 from 110 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
If we divide 290 by 81, we get 3 and a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 10543.913
If we take 243 away from 290, we end up 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.

On to step 10:
If we divide 470 by 81, we get 5 and a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 10543.9135
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.

Moving on to step 11:
650 divided by 81 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 10543.91358
Subtract 648 from 650 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
When dividing 20 by 81, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 10543.91358
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.

Moving on to step 13:
When dividing 200 by 81, we get 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 10543.9135802
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
81 goes into 380 4 times with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 10543.91358024
Deduct 324 from 380 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 10543.91358024, with a leftover of 5.6e-08.
