We look at the division of 320328 by 33 
The aim is to understand the frequency of 33 in 320328.

Step 1:
When dividing 3 by 33, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 33

On to step 2:
32 divided by 33 is 0 with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 32 and we're left with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 33

Moving on to step 3:
If we divide 320 by 33, we get 9 and a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 297 from 320 leaves us with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 33

Step 4:
33 can be fit into 233 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
If we take 231 away from 233, we end up with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 33

On to step 5:
If we divide 22 by 33, we get 0 and a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 970.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 33

Moving on to step 6:
If we divide 228 by 33, we get 6 and a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 9706.0
Deduct 198 from 228 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.

On to step 7:
When dividing 300 by 33, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9706.9
Subtracting 297 from 300 leaves us 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 8:
33 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 9706.9
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.

Step 9:
33 can be fit into 300 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9706.909
Deduct 297 from 300 and we're left 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.

Advancing to step 10:
The number 33 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 9706.909
If we subtract 0 from 30, we 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.

Advancing to step 11:
33 can be fit into 300 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9706.90909
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.

Step 12:
If we divide 30 by 33, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 9706.90909
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.

Going ahead to step 13:
33 can be fit into 300 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 9706.9090909
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.

Moving on to step 14:
33 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9706.9090909
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.

The final result is 9706.9090909 with a remainder of 3e-08.
