Let's divide 598130 by 20
The aim is to understand the frequency of 20 in 598130.

On to step 1:
20 goes into 5 0 times with 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.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 20

Advancing to step 2:
20 can be fit into 59 2 times, resulting in a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 40 from 59 and we're left with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 20

Going ahead to step 3:
When dividing 198 by 20, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtract 180 from 198 to get 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 20

Advancing to step 4:
20 can be fit into 181 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 299.0
Subtracting 180 from 181 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 20

On to step 5:
20 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 2990.0
Subtract 0 from 13 to get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 20

On to step 6:
130 divided by 20 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 29906.0
Subtracting 120 from 130 leaves us 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 7:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 29906.5
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.

Let's proceed to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 29906.5
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 29906.5
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.

The final outcome is 29906.5, with a leftover of 0.0.
