We divide 575900 by 20
The aim is to understand the frequency of 20 in 575900.

On to step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

Moving on 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
If we subtract 40 from 57, we get 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 20

Let's proceed to step 3:
20 goes into 175 8 times with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 28.0
The remainder is 15 after subtracting 160 from 175.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 20

Let's proceed to step 4:
159 divided by 20 is 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 287.0
The remainder is 19 after subtracting 140 from 159.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 20

On to step 5:
20 goes into 190 9 times with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 2879.0
If we take 180 away from 190, we end up with 10.
Fetch the next digit (0) from the dividend, attach it to 10 and continue: 100 / 20

Let's proceed to step 6:
If we divide 100 by 20, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 28795.0
Subtract 100 from 100 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.

On to step 7:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28795.0
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.

Step 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28795.0
Subtracting 0 from 0 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.

In conclusion, the division gives 28795.0 with a balance of 0.0.
