Let's divide 916311 by 33
The aim is to understand the frequency of 33 in 916311.

Advancing to step 1:
9 divided by 33 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 33

Moving on to step 2:
If we divide 91 by 33, we get 2 and a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 66 from 91 and we're left with 25.
Include the next digit (6) from the dividend after 25, then repeat: 256 / 33

Going ahead to step 3:
33 goes into 256 7 times with a remainder of 25.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 231 from 256 leaves us with 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 33

On to step 4:
When dividing 253 by 33, we get 7 with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 277.0
If we take 231 away from 253, we end up with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 33

On to step 5:
221 divided by 33 is 6 with a remainder of 23.
The next digit of our result is 6. 
Result so far: 2776.0
If we subtract 198 from 221, we get 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 33

Moving on to step 6:
231 divided by 33 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 27767.0
If we subtract 231 from 231, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
When dividing 0 by 33, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 27767.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
33 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 27767.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 27767.0 with a remaining 0.0.
