457205 ÷ 20 
We want to divide 457205 by 20.

Let's proceed to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 20

Going ahead to step 2:
If we divide 45 by 20, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 40 from 45 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 20

Advancing to step 3:
If we divide 57 by 20, we get 2 and a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 22.0
Deduct 40 from 57 and we're left with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 20

Moving on to step 4:
If we divide 172 by 20, we get 8 and a remainder of 12.
The next digit of our result is 8. 
Result so far: 228.0
Subtract 160 from 172 to get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 20

Moving on to step 5:
When dividing 120 by 20, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 2286.0
Deduct 120 from 120 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 20

Advancing to step 6:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 22860.0
If we subtract 0 from 5, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 20, we get 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 22860.2
If we take 40 away from 50, we end up 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.

Advancing to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 22860.25
The remainder is 0 after subtracting 100 from 100.
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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 22860.25
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.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 22860.25
Deduct 0 from 0 and we're left 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 22860.25 with a remaining 0.0.
