We look at the division of 459750 by 20 
Let's see how many times 20 fits into 459750.

On 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
If we subtract 0 from 4, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 20

Advancing to step 2:
20 goes into 45 2 times with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 40 away from 45, we end up with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 20

Let's proceed to step 3:
If we divide 59 by 20, we get 2 and a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 40 from 59 and we're left with 19.
Fetch the next digit (7) from the dividend, attach it to 19 and continue: 197 / 20

On to step 4:
20 can be fit into 197 9 times, resulting in a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 229.0
Deduct 180 from 197 and we're left with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 20

Going ahead to step 5:
20 goes into 175 8 times with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 2298.0
If we take 160 away from 175, we end up with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 20

Advancing to step 6:
20 can be fit into 150 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 22987.0
Deduct 140 from 150 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.
Put 5 as the next digit of the answer. 
Result so far: 22987.5
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.

Moving on to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22987.5
The remainder is 0 after subtracting 0 from 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 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22987.5
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.

Our division results in 22987.5 with a remaining 0.0.
