We look at the division of 20410823 by 81 
We want to divide 20410823 by 81.

Moving on to step 1:
2 divided by 81 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 81

Moving on to step 2:
81 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 81

Moving on to step 3:
204 divided by 81 is 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 162 away from 204, we end up with 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 81

Going ahead to step 4:
If we divide 421 by 81, we get 5 and a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 405 from 421 and we're left with 16.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 81

Advancing to step 5:
81 can be fit into 160 1 times, resulting in a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
Subtracting 81 from 160 leaves us with 79.
Take the next digit (8) from the dividend and append it to 79, then repeat: 798 / 81

Advancing to step 6:
81 can be fit into 798 9 times, resulting in a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 2519.0
Deduct 729 from 798 and we're left with 69.
Include the next digit (2) from the dividend after 69, then repeat: 692 / 81

On to step 7:
The number 81 fits into 692 8 times, leaving a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 25198.0
Deduct 648 from 692 and we're left with 44.
Take the next digit (3) from the dividend and append it to 44, then repeat: 443 / 81

Step 8:
If we divide 443 by 81, we get 5 and a remainder of 38.
The number 5 becomes the next digit in our result. 
Result so far: 251985.0
Subtract 405 from 443 to 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.

Moving on to step 9:
When dividing 380 by 81, we get 4 with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 251985.4
The remainder is 56 after subtracting 324 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
If we divide 560 by 81, we get 6 and a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 251985.46
Subtracting 486 from 560 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 11:
When dividing 740 by 81, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 251985.469
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.

Advancing to step 12:
If we divide 110 by 81, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 251985.4691
Deduct 81 from 110 and we're left 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.

Step 13:
The number 81 fits into 290 3 times, leaving a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 251985.46913
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.

Advancing to step 14:
If we divide 470 by 81, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 251985.469135
Subtract 405 from 470 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 15:
When dividing 650 by 81, we get 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 251985.4691358
Subtracting 648 from 650 leaves us 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.

Let's proceed to step 16:
20 divided by 81 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 251985.4691358
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 251985.4691358 with a remainder of 2e-08.
