Let's divide 135001 by 66
The aim is to understand the frequency of 66 in 135001.

On to step 1:
1 divided by 66 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 66

Step 2:
66 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 66

Moving on to step 3:
66 goes into 135 2 times with a remainder of 3.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 132 from 135 leaves us with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 66

Going ahead to step 4:
The number 66 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 30, we end up with 30.
Bring next digit (0) of the dividend behind the 30 and repeat the process: 300 / 66

Moving on to step 5:
If we divide 300 by 66, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 204.0
Subtract 264 from 300 to get 36.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 66

Step 6:
66 can be fit into 361 5 times, resulting in a remainder of 31.
The next digit of our result is 5. 
Result so far: 2045.0
Deduct 330 from 361 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
66 can be fit into 310 4 times, resulting in a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 2045.4
If we take 264 away from 310, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
If we divide 460 by 66, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 2045.46
Deduct 396 from 460 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
640 divided by 66 is 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 2045.469
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 10:
66 can be fit into 460 6 times, resulting in a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 2045.4696
Subtract 396 from 460 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 11:
When dividing 640 by 66, we get 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 2045.46969
If we take 594 away from 640, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 12:
If we divide 460 by 66, we get 6 and a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 2045.469696
If we subtract 396 from 460, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
640 divided by 66 is 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 2045.4696969
The remainder is 46 after subtracting 594 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 14:
The number 66 fits into 460 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 2045.46969696
Subtracting 396 from 460 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 2045.46969696 with a remainder of 6.4e-08.
