We're dividing 811290 by 20 
Let's see how many times 20 fits into 811290.

Moving on to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 20

Advancing to step 2:
20 goes into 81 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 80 from 81, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 20

Let's proceed to step 3:
If we divide 11 by 20, we get 0 and a remainder of 11.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 11 leaves us with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 20

On to step 4:
If we divide 112 by 20, we get 5 and a remainder of 12.
The number 5 becomes the next digit in our result. 
Result so far: 405.0
Deduct 100 from 112 and we're left with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 20

Let's proceed to step 5:
When dividing 129 by 20, we get 6 with a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 4056.0
If we take 120 away from 129, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 20

Step 6:
If we divide 90 by 20, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 40564.0
If we subtract 80 from 90, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 40564.5
If we take 100 away from 100, we end up 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.

Step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40564.5
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40564.5
The remainder is 0 after subtracting 0 from 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 quotient of the division is 40564.5, and the remainder is 0.0.
