We look at the division of 305089 by 33 
The aim is to understand the frequency of 33 in 305089.

Going ahead to step 1:
If we divide 3 by 33, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 33

Step 2:
30 divided by 33 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 33

Let's proceed to step 3:
33 goes into 305 9 times with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 297 away from 305, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 33

Moving on to step 4:
33 goes into 80 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 92.0
If we subtract 66 from 80, we get 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 33

Advancing to step 5:
If we divide 148 by 33, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 924.0
If we take 132 away from 148, we end up with 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 33

Advancing to step 6:
169 divided by 33 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 9245.0
If we take 165 away from 169, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 33 fits into 40 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 9245.1
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
70 divided by 33 is 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 9245.12
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
If we divide 40 by 33, we get 1 and a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 9245.121
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
70 divided by 33 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 9245.1212
Deduct 66 from 70 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 11:
40 divided by 33 is 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 9245.12121
Subtract 33 from 40 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 12:
70 divided by 33 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 9245.121212
Subtracting 66 from 70 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
If we divide 40 by 33, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 9245.1212121
If we take 33 away from 40, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
If we divide 70 by 33, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 9245.12121212
Subtract 66 from 70 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 9245.12121212 with a remaining 4e-09.
