We look at the division of 92502909 by 135 
The aim is to understand the frequency of 135 in 92502909.

On to step 1:
If we divide 9 by 135, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (2) of the dividend behind the 9 and repeat the process: 92 / 135

On to step 2:
135 can be fit into 92 0 times, resulting in a remainder of 92.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 92, we get 92.
Append the next digit (5) from the dividend to 92 and continue with: 925 / 135

Going ahead to step 3:
135 goes into 925 6 times with a remainder of 115.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 810 from 925, we get 115.
Bring next digit (0) of the dividend behind the 115 and repeat the process: 1150 / 135

Step 4:
135 goes into 1150 8 times with a remainder of 70.
The next digit of our result is 8. 
Result so far: 68.0
Deduct 1080 from 1150 and we're left with 70.
Grab the next digit (2) from the dividend, add it to 70, then carry on: 702 / 135

Let's proceed to step 5:
135 can be fit into 702 5 times, resulting in a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 685.0
Deduct 675 from 702 and we're left with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 135

Advancing to step 6:
The number 135 fits into 279 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 6852.0
Subtracting 270 from 279 leaves us with 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 135

Moving on to step 7:
When dividing 90 by 135, we get 0 with a remainder of 90.
The next digit of our result is 0. 
Result so far: 68520.0
Subtract 0 from 90 to get 90.
Take the next digit (9) from the dividend and append it to 90, then repeat: 909 / 135

Step 8:
The number 135 fits into 909 6 times, leaving a remainder of 99.
Use 6 as the next digit of our solution. 
Result so far: 685206.0
If we subtract 810 from 909, we get 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 9:
990 divided by 135 is 7 with a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 685206.7
If we subtract 945 from 990, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 10:
135 goes into 450 3 times with a remainder of 45.
The next digit of our result is 3. 
Result so far: 685206.73
Subtracting 405 from 450 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 11:
The number 135 fits into 450 3 times, leaving a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 685206.733
Deduct 405 from 450 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The quotient of the division is 685206.733, and the remainder is 0.0045.
