We divide 454996 by 20
Our goal is to divide 454996 by 20.

Moving on to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
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

Advancing to step 2:
20 can be fit into 45 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 40 from 45 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 20

Let's proceed to step 3:
20 can be fit into 54 2 times, resulting in a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 40 from 54 and we're left with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 20

On to step 4:
The number 20 fits into 149 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 227.0
If we take 140 away from 149, we end up with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 20

Going ahead to step 5:
The number 20 fits into 99 4 times, leaving a remainder of 19.
The number 4 becomes the next digit in our result. 
Result so far: 2274.0
Subtract 80 from 99 to get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 20

Moving on to step 6:
20 can be fit into 196 9 times, resulting in a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 22749.0
Subtracting 180 from 196 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
The number 20 fits into 160 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 22749.8
Subtracting 160 from 160 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.

Step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22749.8
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.

On to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22749.8
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.

The final outcome is 22749.8, with a leftover of 0.0.
