We look at the division of 48780 by 20 
We want to divide 48780 by 20.

Let's proceed to 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.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 20

Step 2:
If we divide 48 by 20, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 8 after subtracting 40 from 48.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 20

Going ahead to step 3:
When dividing 87 by 20, we get 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 24.0
If we take 80 away from 87, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 20

Moving on to step 4:
20 goes into 78 3 times with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 243.0
If we subtract 60 from 78, we get 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 20

Advancing to step 5:
180 divided by 20 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 2439.0
If we subtract 180 from 180, 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.

Step 6:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2439.0
If we subtract 0 from 0, 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.

Let's proceed to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2439.0
If we subtract 0 from 0, 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.

The final result is 2439.0 with a remainder of 0.0.
