25149 ÷ 3 
The aim is to understand the frequency of 3 in 25149.

Going ahead to step 1:
3 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

Let's proceed to step 2:
The number 3 fits into 25 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 24 from 25 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

Let's proceed to step 3:
3 can be fit into 11 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 83.0
If we take 9 away from 11, we end up with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 3

On to step 4:
The number 3 fits into 24 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 838.0
If we take 24 away from 24, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 3

On to step 5:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 8383.0
The remainder is 0 after subtracting 9 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 6:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8383.0
If we take 0 away from 0, we end up 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.

Step 7:
3 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8383.0
If we subtract 0 from 0, 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.

Our division results in 8383.0 with a remaining 0.0.
