Let's divide 249885 by 3
The aim is to understand the frequency of 3 in 249885.

Step 1:
If we divide 2 by 3, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

Step 2:
When dividing 24 by 3, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 24 from 24 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 3

Moving on to step 3:
When dividing 9 by 3, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
Subtracting 9 from 9 leaves us with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 3

Moving on to step 4:
The number 3 fits into 8 2 times, leaving a remainder of 2.
The next digit of our result is 2. 
Result so far: 832.0
If we take 6 away from 8, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 3

On to step 5:
3 can be fit into 28 9 times, resulting in a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 8329.0
If we subtract 27 from 28, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 3

Going ahead to step 6:
3 can be fit into 15 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 83295.0
The remainder is 0 after subtracting 15 from 15.
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 7:
The number 3 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 83295.0
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 8:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 83295.0
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.

In conclusion, the division gives 83295.0 with a balance of 0.0.
