We look at the division of 527535 by 33 
The aim is to understand the frequency of 33 in 527535.

Going ahead to step 1:
33 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 33

Let's proceed to step 2:
The number 33 fits into 52 1 times, leaving a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 19 after subtracting 33 from 52.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 33

Going ahead to step 3:
197 divided by 33 is 5 with a remainder of 32.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 32 after subtracting 165 from 197.
Include the next digit (5) from the dividend after 32, then repeat: 325 / 33

On to step 4:
If we divide 325 by 33, we get 9 and a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Subtracting 297 from 325 leaves us with 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 33

Moving on to step 5:
33 goes into 283 8 times with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 1598.0
Deduct 264 from 283 and we're left with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 33

Going ahead to step 6:
If we divide 195 by 33, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 15985.0
Deduct 165 from 195 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 7:
If we divide 300 by 33, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 15985.9
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 8:
33 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 15985.9
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
33 goes into 300 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 15985.909
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
30 divided by 33 is 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 15985.909
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 33 fits into 300 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 15985.90909
If we take 297 away from 300, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
33 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 15985.90909
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 13:
If we divide 300 by 33, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 15985.9090909
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 14:
If we divide 30 by 33, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 15985.9090909
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 15985.9090909 with a remaining 3e-08.
