We look at the division of 24723 by 20 
We're looking to find how many times 20 goes into 24723.

Going ahead to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 20

On to step 2:
If we divide 24 by 20, we get 1 and a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 4 after subtracting 20 from 24.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 20

Going ahead to step 3:
If we divide 47 by 20, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtracting 40 from 47 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 20

Going ahead to step 4:
20 goes into 72 3 times with a remainder of 12.
The next digit of our result is 3. 
Result so far: 123.0
Subtracting 60 from 72 leaves us with 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 20

On to step 5:
If we divide 123 by 20, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 1236.0
If we subtract 120 from 123, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1236.1
Deduct 20 from 30 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1236.15
If we take 100 away from 100, 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 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1236.15
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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1236.15
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.

Our division results in 1236.15 with a remaining 0.0.
