We look at the division of 913073 by 33 
The aim is to understand the frequency of 33 in 913073.

Let's proceed to step 1:
The number 33 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 33

Moving on to step 2:
91 divided by 33 is 2 with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 25 after subtracting 66 from 91.
Fetch the next digit (3) from the dividend, attach it to 25 and continue: 253 / 33

Let's proceed to step 3:
253 divided by 33 is 7 with a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 27.0
The remainder is 22 after subtracting 231 from 253.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 33

Going ahead to step 4:
If we divide 220 by 33, we get 6 and a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 276.0
If we subtract 198 from 220, we get 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 33

Let's proceed to step 5:
The number 33 fits into 227 6 times, leaving a remainder of 29.
The next digit of our result is 6. 
Result so far: 2766.0
Subtracting 198 from 227 leaves us with 29.
Take the next digit (3) from the dividend and append it to 29, then repeat: 293 / 33

Going ahead to step 6:
If we divide 293 by 33, we get 8 and a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 27668.0
If we take 264 away from 293, we end up with 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 7:
When dividing 290 by 33, we get 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 27668.8
Deduct 264 from 290 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
33 can be fit into 260 7 times, resulting in a remainder of 29.
The next digit of our result is 7. 
Result so far: 27668.87
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.

Step 9:
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: 27668.878
Subtracting 264 from 290 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 10:
33 can be fit into 260 7 times, resulting in a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 27668.8787
If we take 231 away from 260, we end up with 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 11:
The number 33 fits into 290 8 times, leaving a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 27668.87878
Deduct 264 from 290 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
When dividing 260 by 33, we get 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 27668.878787
Deduct 231 from 260 and we're left with 29.
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:
33 can be fit into 290 8 times, resulting in a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 27668.8787878
Deduct 264 from 290 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
33 goes into 260 7 times with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 27668.87878787
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 result is 27668.87878787 with a remainder of 2.9e-08.
