We look at the division of 64675244 by 20 
The aim is to understand the frequency of 20 in 64675244.

Going ahead to step 1:
20 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 20

On to step 2:
When dividing 64 by 20, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 60 away from 64, we end up with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 20

Let's proceed to step 3:
20 can be fit into 46 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we take 40 away from 46, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 20

Advancing to step 4:
67 divided by 20 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 323.0
If we subtract 60 from 67, we get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 20

Moving on to step 5:
20 can be fit into 75 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 3233.0
If we take 60 away from 75, we end up with 15.
Fetch the next digit (2) from the dividend, attach it to 15 and continue: 152 / 20

Let's proceed to step 6:
The number 20 fits into 152 7 times, leaving a remainder of 12.
The next digit of our result is 7. 
Result so far: 32337.0
Deduct 140 from 152 and we're left with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 20

Moving on to step 7:
124 divided by 20 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 323376.0
Subtract 120 from 124 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 20

Advancing to step 8:
44 divided by 20 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 3233762.0
Subtracting 40 from 44 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
The number 20 fits into 40 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 3233762.2
Subtracting 40 from 40 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.

Let's proceed to step 10:
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: 3233762.2
If we take 0 away from 0, 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.

Advancing to step 11:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3233762.2
If we subtract 0 from 0, 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.

The final outcome is 3233762.2, with a leftover of 0.0.
