820768 ÷ 20 
We want to divide 820768 by 20.

Step 1:
The number 20 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (2) from the dividend, add it to 8, then carry on: 82 / 20

Moving on to step 2:
If we divide 82 by 20, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 80 from 82 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 20

Let's proceed to step 3:
20 divided by 20 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 41.0
Deduct 20 from 20 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 20

Advancing to step 4:
When dividing 7 by 20, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 410.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 20

Advancing to step 5:
20 can be fit into 76 3 times, resulting in a remainder of 16.
The next digit of our result is 3. 
Result so far: 4103.0
The remainder is 16 after subtracting 60 from 76.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 20

Moving on to step 6:
If we divide 168 by 20, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 41038.0
Subtract 160 from 168 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
20 can be fit into 80 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 41038.4
The remainder is 0 after subtracting 80 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 41038.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 41038.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 41038.4 and a remainder of 0.0.
