We look at the division of 457768 by 20 
We want to divide 457768 by 20.

On to step 1:
When dividing 4 by 20, we get 0 with 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.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 20

On to step 2:
The number 20 fits into 45 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 40 from 45 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

Advancing to step 3:
20 goes into 57 2 times with a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 17 after subtracting 40 from 57.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 20

Step 4:
The number 20 fits into 177 8 times, leaving a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 228.0
The remainder is 17 after subtracting 160 from 177.
Fetch the next digit (6) from the dividend, attach it to 17 and continue: 176 / 20

Going ahead to step 5:
When dividing 176 by 20, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 2288.0
Subtract 160 from 176 to get 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 20

Step 6:
20 goes into 168 8 times with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 22888.0
The remainder is 8 after subtracting 160 from 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
The number 20 fits into 80 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 22888.4
Deduct 80 from 80 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.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22888.4
If we subtract 0 from 0, 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.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22888.4
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.

In conclusion, the division gives 22888.4 with a balance of 0.0.
