We're dividing 457640 by 20 
We want to divide 457640 by 20.

Moving on to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 20

Let's proceed to step 2:
If we divide 45 by 20, we get 2 and a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 40 away from 45, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 20

Let's proceed to step 3:
57 divided by 20 is 2 with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 40 from 57 to get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 20

Advancing to step 4:
20 can be fit into 176 8 times, resulting in a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 228.0
Subtract 160 from 176 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 20

Going ahead to step 5:
20 can be fit into 164 8 times, resulting in a remainder of 4.
The next digit of our result is 8. 
Result so far: 2288.0
If we subtract 160 from 164, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 20

Moving on to step 6:
20 goes into 40 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 22882.0
If we subtract 40 from 40, 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.

Moving on to step 7:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 22882.0
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.

Going ahead to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 22882.0
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.

The quotient of the division is 22882.0, and the remainder is 0.0.
