We look at the division of 594244 by 20 
The aim is to understand the frequency of 20 in 594244.

Moving on to step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 20

Advancing to step 2:
The number 20 fits into 59 2 times, leaving a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 40 from 59 to get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 20

On to step 3:
The number 20 fits into 194 9 times, leaving a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtract 180 from 194 to get 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 20

On to step 4:
When dividing 142 by 20, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 297.0
Deduct 140 from 142 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 20

Step 5:
When dividing 24 by 20, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 2971.0
Subtract 20 from 24 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 20

Going ahead to step 6:
The number 20 fits into 44 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 29712.0
If we subtract 40 from 44, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 29712.2
If we take 40 away from 40, 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.

Step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 29712.2
Deduct 0 from 0 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.

Moving on to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 29712.2
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.

The final result is 29712.2 with a remainder of 0.0.
