We look at the division of 50075 by 20 
The aim is to understand the frequency of 20 in 50075.

Let's proceed to step 1:
5 divided by 20 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 20

Step 2:
When dividing 50 by 20, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 10 after subtracting 40 from 50.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 20

Moving on to step 3:
If we divide 100 by 20, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Subtract 100 from 100 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 20

Let's proceed to step 4:
The number 20 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 250.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 20

Going ahead to step 5:
20 goes into 75 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 2503.0
If we subtract 60 from 75, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 6:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 2503.7
If we take 140 away from 150, 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.

Going ahead to step 7:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 2503.75
If we subtract 100 from 100, 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.

Advancing to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2503.75
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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2503.75
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.

The quotient of the division is 2503.75, and the remainder is 0.0.
