We're dividing 482940 by 20 
We want to divide 482940 by 20.

Step 1:
20 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 20

Step 2:
20 goes into 48 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2.0
If we take 40 away from 48, we end up with 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 20

Going ahead to step 3:
82 divided by 20 is 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 (9) from the dividend and append it to 2, then repeat: 29 / 20

Moving on to step 4:
20 can be fit into 29 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 241.0
Subtracting 20 from 29 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 20

Step 5:
If we divide 94 by 20, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 2414.0
If we subtract 80 from 94, we get 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 20

Step 6:
140 divided by 20 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 24147.0
If we subtract 140 from 140, 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.

Advancing to step 7:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 24147.0
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.

Advancing to step 8:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24147.0
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 24147.0 with a remainder of 0.0.
