We look at the division of 339665 by 33 
The aim is to understand the frequency of 33 in 339665.

Step 1:
33 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 33

Step 2:
If we divide 33 by 33, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 0 after subtracting 33 from 33.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 33

Let's proceed to step 3:
If we divide 9 by 33, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 9 to get 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 33

Going ahead to step 4:
33 goes into 96 2 times with a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Deduct 66 from 96 and we're left with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 33

Let's proceed to step 5:
33 goes into 306 9 times with a remainder of 9.
The next digit of our result is 9. 
Result so far: 1029.0
Deduct 297 from 306 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 33

On to step 6:
The number 33 fits into 95 2 times, leaving a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 10292.0
The remainder is 29 after subtracting 66 from 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
If we divide 290 by 33, we get 8 and a remainder of 26.
The next digit of our result is 8. 
Result so far: 10292.8
Subtract 264 from 290 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
If we divide 260 by 33, we get 7 and a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 10292.87
If we subtract 231 from 260, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 9:
If we divide 290 by 33, we get 8 and a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 10292.878
If we subtract 264 from 290, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
33 can be fit into 260 7 times, resulting in a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 10292.8787
Subtract 231 from 260 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 11:
290 divided by 33 is 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 10292.87878
If we subtract 264 from 290, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
If we divide 260 by 33, we get 7 and a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 10292.878787
The remainder is 29 after subtracting 231 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
The number 33 fits into 290 8 times, leaving a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 10292.8787878
Subtract 264 from 290 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
The number 33 fits into 260 7 times, leaving a remainder of 29.
The next digit of our result is 7. 
Result so far: 10292.87878787
Subtract 231 from 260 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 10292.87878787, with a leftover of 2.9e-08.
