We're dividing 9235 by 3 
The aim is to understand the frequency of 3 in 9235.

Step 1:
When dividing 9 by 3, we get 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 9 from 9, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Moving on to step 2:
When dividing 2 by 3, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 3

Let's proceed to step 3:
23 divided by 3 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 307.0
Deduct 21 from 23 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

Advancing to step 4:
3 can be fit into 25 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 3078.0
Subtracting 24 from 25 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 5:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3078.3
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 6:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 3078.33
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 3078.33 with a remaining 0.001.
