We look at the division of 458130 by 20 
We're looking to find how many times 20 goes into 458130.

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
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 20

On to step 2:
20 goes into 45 2 times with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 5 after subtracting 40 from 45.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 20

Moving on to step 3:
If we divide 58 by 20, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 40 from 58 leaves us with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 20

Advancing to step 4:
If we divide 181 by 20, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 229.0
If we take 180 away from 181, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 20

Advancing to step 5:
20 can be fit into 13 0 times, resulting in a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 2290.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 20

On to step 6:
The number 20 fits into 130 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 22906.0
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
20 goes into 100 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 22906.5
If we subtract 100 from 100, 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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22906.5
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.

On to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22906.5
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.

Our division results in 22906.5 with a remaining 0.0.
