We divide 15135 by 20
The aim is to understand the frequency of 20 in 15135.

Moving on to step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 20

Advancing to step 2:
20 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 20

Let's proceed to step 3:
If we divide 151 by 20, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 140 from 151 leaves us with 11.
Fetch the next digit (3) from the dividend, attach it to 11 and continue: 113 / 20

Let's proceed to step 4:
113 divided by 20 is 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtracting 100 from 113 leaves us with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 20

Let's proceed to step 5:
20 can be fit into 135 6 times, resulting in a remainder of 15.
The next digit of our result is 6. 
Result so far: 756.0
Subtract 120 from 135 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 6:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 756.7
Deduct 140 from 150 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.

On to step 7:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 756.75
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 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: 756.75
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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 756.75
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.

In conclusion, the division gives 756.75 with a balance of 0.0.
