We look at the division of 455824 by 20 
We want to figure out the number of times 455824 can be divided by 20.

Moving on to step 1:
4 divided by 20 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 20

Step 2:
20 goes into 45 2 times with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 40 away from 45, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 20

Let's proceed to step 3:
If we divide 55 by 20, we get 2 and a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
The remainder is 15 after subtracting 40 from 55.
Take the next digit (8) from the dividend and append it to 15, then repeat: 158 / 20

Going ahead to step 4:
20 can be fit into 158 7 times, resulting in a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 227.0
Subtract 140 from 158 to get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 20

Moving on to step 5:
If we divide 182 by 20, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 2279.0
If we take 180 away from 182, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 20

On to step 6:
If we divide 24 by 20, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 22791.0
Subtracting 20 from 24 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
20 goes into 40 2 times with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 22791.2
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22791.2
Deduct 0 from 0 and we're left 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.

Going ahead to step 9:
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: 22791.2
Deduct 0 from 0 and we're left 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 result is 22791.2 with a remainder of 0.0.
