We divide 233663 by 3
The aim is to understand the frequency of 3 in 233663.

On to step 1:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 3

Let's proceed to step 2:
When dividing 23 by 3, we get 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
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:
23 divided by 3 is 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 77.0
Subtracting 21 from 23 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 3

Moving on to step 4:
26 divided by 3 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 778.0
Subtract 24 from 26 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 3

Advancing to step 5:
The number 3 fits into 26 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 7788.0
Subtract 24 from 26 to get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 3

Moving on to step 6:
3 can be fit into 23 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 77887.0
Subtract 21 from 23 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 77887.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 77887.66
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 77887.66 and a remainder of 0.002.
