We look at the division of 453975 by 20 
Let's see how many times 20 fits into 453975.

Moving on to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
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

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
Subtracting 40 from 45 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 20

Going ahead to step 3:
53 divided by 20 is 2 with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 22.0
If we subtract 40 from 53, we get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 20

Moving on to step 4:
139 divided by 20 is 6 with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 226.0
Subtract 120 from 139 to get 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 20

Moving on to step 5:
20 goes into 197 9 times with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 2269.0
If we take 180 away from 197, we end up with 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 20

Step 6:
20 can be fit into 175 8 times, resulting in a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 22698.0
Subtract 160 from 175 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 22698.7
If we subtract 140 from 150, 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 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 22698.75
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.

On to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 22698.75
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.

On to step 10:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22698.75
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 quotient of the division is 22698.75, and the remainder is 0.0.
