452453 divided by 20 
The aim is to understand the frequency of 20 in 452453.

Moving on to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 20

Going ahead to step 2:
When dividing 45 by 20, we get 2 with 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.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 20

Step 3:
52 divided by 20 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 40 from 52 to get 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 20

Step 4:
The number 20 fits into 124 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 226.0
Subtracting 120 from 124 leaves us with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 20

Going ahead to step 5:
If we divide 45 by 20, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 2262.0
The remainder is 5 after subtracting 40 from 45.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 20

On to step 6:
If we divide 53 by 20, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 22622.0
The remainder is 13 after subtracting 40 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
When dividing 130 by 20, we get 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 22622.6
If we take 120 away from 130, 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.
Record the quotient 5 as the next digit in the result. 
Result so far: 22622.65
If we take 100 away from 100, we end up 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.

Going ahead to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 22622.65
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:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 22622.65
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.

In conclusion, the division gives 22622.65 with a balance of 0.0.
