We look at the division of 936817 by 33 
The aim is to understand the frequency of 33 in 936817.

Step 1:
When dividing 9 by 33, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 33

Going ahead to step 2:
33 can be fit into 93 2 times, resulting in a remainder of 27.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 66 from 93 leaves us with 27.
Bring next digit (6) of the dividend behind the 27 and repeat the process: 276 / 33

Let's proceed to step 3:
If we divide 276 by 33, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 264 away from 276, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 33

Going ahead to step 4:
33 goes into 128 3 times with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 283.0
If we take 99 away from 128, we end up with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 33

Advancing to step 5:
291 divided by 33 is 8 with a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 2838.0
Subtract 264 from 291 to get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 33

Going ahead to step 6:
When dividing 277 by 33, we get 8 with a remainder of 13.
Put 8 as the next digit of the answer. 
Result so far: 28388.0
Subtracting 264 from 277 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
33 can be fit into 130 3 times, resulting in a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 28388.3
Subtracting 99 from 130 leaves us 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.

Step 8:
If we divide 310 by 33, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 28388.39
If we subtract 297 from 310, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
130 divided by 33 is 3 with a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 28388.393
Subtract 99 from 130 to 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.

Step 10:
If we divide 310 by 33, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 28388.3939
Subtract 297 from 310 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
If we divide 130 by 33, we get 3 and a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 28388.39393
If we take 99 away from 130, we end up 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.

Let's proceed to step 12:
33 goes into 310 9 times with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 28388.393939
The remainder is 13 after subtracting 297 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 13:
33 can be fit into 130 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 28388.3939393
Deduct 99 from 130 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.

Moving on to step 14:
If we divide 310 by 33, we get 9 and a remainder of 13.
The next digit of our result is 9. 
Result so far: 28388.39393939
The remainder is 13 after subtracting 297 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Our division results in 28388.39393939 with a remaining 1.3e-08.
