Let's divide 559593 by 20
The aim is to understand the frequency of 20 in 559593.

Moving on to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 20

Step 2:
The number 20 fits into 55 2 times, leaving a remainder of 15.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 40 from 55 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 20

Step 3:
When dividing 159 by 20, we get 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we take 140 away from 159, we end up with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 20

Moving on to step 4:
195 divided by 20 is 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 279.0
Subtract 180 from 195 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 20

Let's proceed to step 5:
20 can be fit into 159 7 times, resulting in a remainder of 19.
The next digit of our result is 7. 
Result so far: 2797.0
The remainder is 19 after subtracting 140 from 159.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 20

Going ahead to step 6:
193 divided by 20 is 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 27979.0
If we take 180 away from 193, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
130 divided by 20 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 27979.6
If we take 120 away from 130, 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.

On to step 8:
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: 27979.65
If we take 100 away from 100, 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.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 27979.65
Subtract 0 from 0 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.

Let's proceed to step 10:
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: 27979.65
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.

The quotient of the division is 27979.65, and the remainder is 0.0.
