Let's divide 572447 by 20
The aim is to understand the frequency of 20 in 572447.

Advancing to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 20

Let's proceed to step 2:
57 divided by 20 is 2 with a remainder of 17.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 40 from 57 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 20

Moving on to step 3:
20 goes into 172 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 160 from 172 to get 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 20

On to step 4:
The number 20 fits into 124 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 286.0
Deduct 120 from 124 and we're left with 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 20

On to step 5:
20 goes into 44 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2862.0
Deduct 40 from 44 and we're left with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 20

Step 6:
20 goes into 47 2 times with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 28622.0
The remainder is 7 after subtracting 40 from 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
When dividing 70 by 20, we get 3 with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 28622.3
Subtract 60 from 70 to 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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 28622.35
Subtracting 100 from 100 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 9:
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: 28622.35
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.

Advancing to step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28622.35
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.

Our division results in 28622.35 with a remaining 0.0.
