We look at the division of 482404 by 20 
We're looking to find how many times 20 goes into 482404.

Moving on to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

On to step 2:
If we divide 48 by 20, we get 2 and a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 40 from 48, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 20

Let's proceed to step 3:
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: 24.0
Deduct 80 from 82 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 20

Moving on to step 4:
20 goes into 24 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 241.0
The remainder is 4 after subtracting 20 from 24.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 20

Moving on to step 5:
40 divided by 20 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2412.0
Deduct 40 from 40 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 20

Advancing to step 6:
20 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 24120.0
If we subtract 0 from 4, we get 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.
Write down 2 as next digit of the result. 
Result so far: 24120.2
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24120.2
If we take 0 away from 0, 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.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 24120.2
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.

The quotient of the division is 24120.2, and the remainder is 0.0.
