We look at the division of 544907 by 20 
The aim is to understand the frequency of 20 in 544907.

Let's proceed 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
Subtract 0 from 5 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 20

On to step 2:
20 goes into 54 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 40 from 54 and we're left with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 20

Advancing to step 3:
144 divided by 20 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 140 from 144 leaves us with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 20

Step 4:
20 can be fit into 49 2 times, resulting in a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 272.0
Deduct 40 from 49 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 20

Step 5:
90 divided by 20 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 2724.0
If we subtract 80 from 90, we get 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 20

On to step 6:
20 goes into 107 5 times with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 27245.0
Deduct 100 from 107 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
The number 20 fits into 70 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 27245.3
Subtracting 60 from 70 leaves us 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.

Step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 27245.35
Deduct 100 from 100 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.
Put 0 as the next digit of the answer. 
Result so far: 27245.35
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.

Let's proceed to step 10:
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: 27245.35
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 27245.35 with a remaining 0.0.
