We look at the division of 290520 by 33 
The aim is to understand the frequency of 33 in 290520.

On to step 1:
33 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 33

Advancing to step 2:
29 divided by 33 is 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 33

Advancing to step 3:
290 divided by 33 is 8 with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 264 from 290, we get 26.
Bring next digit (5) of the dividend behind the 26 and repeat the process: 265 / 33

Step 4:
33 goes into 265 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
If we subtract 264 from 265, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 33

Going ahead to step 5:
If we divide 12 by 33, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 880.0
The remainder is 12 after subtracting 0 from 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 33

Step 6:
33 goes into 120 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 8803.0
If we subtract 99 from 120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
33 goes into 210 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 8803.6
Subtracting 198 from 210 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
The number 33 fits into 120 3 times, leaving a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 8803.63
If we subtract 99 from 120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 9:
33 goes into 210 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 8803.636
Subtract 198 from 210 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
The number 33 fits into 120 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 8803.6363
If we take 99 away from 120, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
When dividing 210 by 33, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 8803.63636
If we subtract 198 from 210, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
120 divided by 33 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 8803.636363
If we subtract 99 from 120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 13:
33 can be fit into 210 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 8803.6363636
Deduct 198 from 210 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
33 can be fit into 120 3 times, resulting in a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 8803.63636363
Deduct 99 from 120 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 8803.63636363 with a remaining 2.1e-08.
