We're dividing 597570 by 20 
The aim is to understand the frequency of 20 in 597570.

Advancing to step 1:
20 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 20

On to step 2:
If we divide 59 by 20, we get 2 and 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.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 20

Going ahead to step 3:
20 goes into 197 9 times with a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
The remainder is 17 after subtracting 180 from 197.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 20

Step 4:
20 can be fit into 175 8 times, resulting in a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 298.0
If we take 160 away from 175, we end up with 15.
Append the next digit (7) from the dividend to 15 and continue with: 157 / 20

Advancing to step 5:
157 divided by 20 is 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 2987.0
Subtracting 140 from 157 leaves us with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 20

Moving on to step 6:
20 goes into 170 8 times with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 29878.0
Subtract 160 from 170 to get 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 7:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 29878.5
If we subtract 100 from 100, 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.

On to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 29878.5
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.

Advancing 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: 29878.5
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.

In conclusion, the division gives 29878.5 with a balance of 0.0.
