Let's divide 579184 by 20
The aim is to understand the frequency of 20 in 579184.

Step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 20

Let's proceed to step 2:
57 divided by 20 is 2 with a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 40 from 57 leaves us with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 20

Step 3:
The number 20 fits into 179 8 times, leaving a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 28.0
Deduct 160 from 179 and we're left with 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 20

Going ahead to step 4:
191 divided by 20 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 289.0
The remainder is 11 after subtracting 180 from 191.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 20

Step 5:
If we divide 118 by 20, we get 5 and a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 2895.0
Deduct 100 from 118 and we're left with 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 20

Step 6:
184 divided by 20 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 28959.0
If we take 180 away from 184, we end up 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.

On to step 7:
20 can be fit into 40 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 28959.2
The remainder is 0 after subtracting 40 from 40.
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 8:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 28959.2
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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28959.2
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 28959.2 with a remainder of 0.0.
