69668335 ÷ 135 
The aim is to understand the frequency of 135 in 69668335.

Step 1:
When dividing 6 by 135, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 135

Advancing to step 2:
135 can be fit into 69 0 times, resulting in a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Bring next digit (6) of the dividend behind the 69 and repeat the process: 696 / 135

Step 3:
135 can be fit into 696 5 times, resulting in a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 675 away from 696, we end up with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 135

Let's proceed to step 4:
If we divide 216 by 135, we get 1 and a remainder of 81.
The next digit of our result is 1. 
Result so far: 51.0
If we subtract 135 from 216, we get 81.
Take the next digit (8) from the dividend and append it to 81, then repeat: 818 / 135

Moving on to step 5:
818 divided by 135 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 516.0
Subtracting 810 from 818 leaves us with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 135

On to step 6:
The number 135 fits into 83 0 times, leaving a remainder of 83.
Use 0 as the next digit of our solution. 
Result so far: 5160.0
Subtract 0 from 83 to get 83.
Append the next digit (3) from the dividend to 83 and continue with: 833 / 135

Let's proceed to step 7:
If we divide 833 by 135, we get 6 and a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 51606.0
If we take 810 away from 833, we end up with 23.
Include the next digit (5) from the dividend after 23, then repeat: 235 / 135

Going ahead to step 8:
135 can be fit into 235 1 times, resulting in a remainder of 100.
Put 1 as the next digit of the answer. 
Result so far: 516061.0
Subtracting 135 from 235 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 9:
When dividing 1000 by 135, we get 7 with a remainder of 55.
The next digit of our result is 7. 
Result so far: 516061.7
The remainder is 55 after subtracting 945 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
The number 135 fits into 550 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 516061.74
Subtract 540 from 550 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 11:
100 divided by 135 is 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 516061.74
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
If we divide 1000 by 135, we get 7 and a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 516061.7407
The remainder is 55 after subtracting 945 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 13:
135 can be fit into 550 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 516061.74074
Subtracting 540 from 550 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 14:
135 can be fit into 100 0 times, resulting in a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 516061.74074
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 15:
135 goes into 1000 7 times with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 516061.7407407
Deduct 945 from 1000 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 16:
If we divide 550 by 135, we get 4 and a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 516061.74074074
The remainder is 10 after subtracting 540 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 516061.74074074 with a remainder of 1e-08.
