Let's divide 485504 by 20
We want to figure out the number of times 485504 can be divided by 20.

Let's proceed to step 1:
4 divided by 20 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 20

Going ahead to step 2:
48 divided by 20 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 40 from 48, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 20

Let's proceed to step 3:
85 divided by 20 is 4 with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 5 after subtracting 80 from 85.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 20

Advancing to step 4:
The number 20 fits into 55 2 times, leaving a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 242.0
If we subtract 40 from 55, we get 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 20

Let's proceed to step 5:
20 can be fit into 150 7 times, resulting in a remainder of 10.
The next digit of our result is 7. 
Result so far: 2427.0
The remainder is 10 after subtracting 140 from 150.
Take the next digit (4) from the dividend and append it to 10, then repeat: 104 / 20

Step 6:
The number 20 fits into 104 5 times, leaving a remainder of 4.
The next digit of our result is 5. 
Result so far: 24275.0
Deduct 100 from 104 and we're left 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.

On to step 7:
40 divided by 20 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 24275.2
If we subtract 40 from 40, 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 8:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 24275.2
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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24275.2
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 final result is 24275.2 with a remainder of 0.0.
