We look at the division of 81262536 by 820 
We're looking to find how many times 820 goes into 81262536.

Advancing to step 1:
8 divided by 820 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 820

Going ahead to step 2:
820 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 820

Moving on to step 3:
If we divide 812 by 820, we get 0 and a remainder of 812.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 812 after subtracting 0 from 812.
Fetch the next digit (6) from the dividend, attach it to 812 and continue: 8126 / 820

On to step 4:
When dividing 8126 by 820, we get 9 with a remainder of 746.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 7380 from 8126, we get 746.
Take the next digit (2) from the dividend and append it to 746, then repeat: 7462 / 820

On to step 5:
When dividing 7462 by 820, we get 9 with a remainder of 82.
The next digit of our result is 9. 
Result so far: 99.0
Subtract 7380 from 7462 to get 82.
Grab the next digit (5) from the dividend, add it to 82, then carry on: 825 / 820

Going ahead to step 6:
825 divided by 820 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 991.0
If we subtract 820 from 825, we get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 820

Advancing to step 7:
When dividing 53 by 820, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 9910.0
Deduct 0 from 53 and we're left with 53.
Append the next digit (6) from the dividend to 53 and continue with: 536 / 820

Going ahead to step 8:
820 can be fit into 536 0 times, resulting in a remainder of 536.
Use 0 as the next digit of our solution. 
Result so far: 99100.0
If we subtract 0 from 536, we get 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 9:
When dividing 5360 by 820, we get 6 with a remainder of 440.
The next digit of our result is 6. 
Result so far: 99100.6
Subtract 4920 from 5360 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 10:
When dividing 4400 by 820, we get 5 with a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 99100.65
Deduct 4100 from 4400 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 11:
When dividing 3000 by 820, we get 3 with a remainder of 540.
The next digit of our result is 3. 
Result so far: 99100.653
Deduct 2460 from 3000 and we're left with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 12:
When dividing 5400 by 820, we get 6 with a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 99100.6536
The remainder is 480 after subtracting 4920 from 5400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
4800 divided by 820 is 5 with a remainder of 700.
Put 5 as the next digit of the answer. 
Result so far: 99100.65365
If we take 4100 away from 4800, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Moving on to step 14:
If we divide 7000 by 820, we get 8 and a remainder of 440.
Write down 8 as next digit of the result. 
Result so far: 99100.653658
Subtract 6560 from 7000 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 15:
If we divide 4400 by 820, we get 5 and a remainder of 300.
The number 5 becomes the next digit in our result. 
Result so far: 99100.6536585
Subtract 4100 from 4400 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 16:
If we divide 3000 by 820, we get 3 and a remainder of 540.
Use 3 as the next digit of our solution. 
Result so far: 99100.65365853
Subtracting 2460 from 3000 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

The final outcome is 99100.65365853, with a leftover of 5.4e-07.
