We're dividing 480942 by 20 
We want to divide 480942 by 20.

Let's proceed 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
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 20

Let's proceed to step 2:
The number 20 fits into 48 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 40 from 48, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 20

Advancing to step 3:
20 goes into 80 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 24.0
Deduct 80 from 80 and we're left with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 20

Let's proceed to step 4:
If we divide 9 by 20, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 240.0
If we take 0 away from 9, we end up with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 20

Moving on to step 5:
When dividing 94 by 20, we get 4 with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 2404.0
Subtracting 80 from 94 leaves us with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 20

Moving on to step 6:
142 divided by 20 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 24047.0
Subtract 140 from 142 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 goes into 20 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 24047.1
If we subtract 20 from 20, 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.

Going ahead to step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 24047.1
Subtracting 0 from 0 leaves us 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.

Let's proceed 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: 24047.1
Subtracting 0 from 0 leaves us 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 24047.1 with a remainder of 0.0.
