826831 divided by 20 
Our goal is to divide 826831 by 20.

On to step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 20

On to step 2:
When dividing 82 by 20, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 80 from 82 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 20

Advancing to step 3:
If we divide 26 by 20, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 20 from 26 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 20

Moving on to step 4:
The number 20 fits into 68 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 413.0
The remainder is 8 after subtracting 60 from 68.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 20

Advancing to step 5:
When dividing 83 by 20, we get 4 with a remainder of 3.
Write down 4 as next digit of the result. 
Result so far: 4134.0
The remainder is 3 after subtracting 80 from 83.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 20

Advancing to step 6:
When dividing 31 by 20, we get 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 41341.0
Deduct 20 from 31 and we're left 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.

Moving on to step 7:
20 can be fit into 110 5 times, resulting in a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 41341.5
The remainder is 10 after subtracting 100 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 41341.55
Subtracting 100 from 100 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 41341.55, with a leftover of 0.0.
