We're dividing 35341 by 66 
The aim is to understand the frequency of 66 in 35341.

On to step 1:
When dividing 3 by 66, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 66

On to step 2:
66 can be fit into 35 0 times, resulting in a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 35, we end up with 35.
Bring next digit (3) of the dividend behind the 35 and repeat the process: 353 / 66

Going ahead to step 3:
66 can be fit into 353 5 times, resulting in a remainder of 23.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 330 from 353, we get 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 66

Step 4:
66 goes into 234 3 times with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Subtract 198 from 234 to get 36.
Bring next digit (1) of the dividend behind the 36 and repeat the process: 361 / 66

Moving on to step 5:
361 divided by 66 is 5 with a remainder of 31.
The next digit of our result is 5. 
Result so far: 535.0
If we subtract 330 from 361, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 6:
66 goes into 310 4 times with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 535.4
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.

Going ahead to step 7:
If we divide 460 by 66, we get 6 and a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 535.46
If we take 396 away from 460, we end up 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.

Advancing to step 8:
66 goes into 640 9 times with a remainder of 46.
The next digit of our result is 9. 
Result so far: 535.469
If we subtract 594 from 640, we get 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 9:
If we divide 460 by 66, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 535.4696
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.

On to step 10:
66 goes into 640 9 times with a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 535.46969
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.

Let's proceed to step 11:
66 goes into 460 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 535.469696
The remainder is 64 after subtracting 396 from 460.
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 12:
If we divide 640 by 66, we get 9 and a remainder of 46.
The next digit of our result is 9. 
Result so far: 535.4696969
Deduct 594 from 640 and we're left 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 13:
460 divided by 66 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 535.46969696
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.

Our division results in 535.46969696 with a remaining 6.4e-08.
