We're dividing 233955 by 3 
The aim is to understand the frequency of 3 in 233955.

Step 1:
3 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
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

Advancing to step 2:
If we divide 23 by 3, we get 7 and a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 21 from 23, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 3

Step 3:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 77.0
If we take 21 away from 23, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 3

Let's proceed to step 4:
If we divide 29 by 3, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 779.0
Deduct 27 from 29 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

On to step 5:
25 divided by 3 is 8 with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 7798.0
Subtracting 24 from 25 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Moving on to step 6:
If we divide 15 by 3, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 77985.0
If we subtract 15 from 15, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 77985.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 3 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 77985.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 77985.0 with a remainder of 0.0.
