We're dividing 576005 by 20 
The aim is to understand the frequency of 20 in 576005.

Let's proceed to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 20

On to step 2:
The number 20 fits into 57 2 times, leaving a remainder of 17.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 40 from 57 leaves us with 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 20

On to step 3:
176 divided by 20 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 160 from 176, we get 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 20

Step 4:
160 divided by 20 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 288.0
Deduct 160 from 160 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 20

Moving on to step 5:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2880.0
If we subtract 0 from 0, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 20

Let's proceed to step 6:
20 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 28800.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
The number 20 fits into 50 2 times, leaving a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 28800.2
Deduct 40 from 50 and we're left 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.

Moving on to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 28800.25
The remainder is 0 after subtracting 100 from 100.
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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28800.25
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.

On to step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28800.25
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.

The final result is 28800.25 with a remainder of 0.0.
