248742 divided by 3 
The aim is to understand the frequency of 3 in 248742.

Step 1:
The number 3 fits into 2 0 times, leaving 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 (4) of the dividend behind the 2 and repeat the process: 24 / 3

Let's proceed to step 2:
24 divided by 3 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 24 from 24, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 3

Moving on to step 3:
3 can be fit into 8 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 82.0
If we take 6 away from 8, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 3

Moving on to step 4:
3 goes into 27 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 829.0
Subtracting 27 from 27 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 3

Going ahead to step 5:
3 goes into 4 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 8291.0
If we take 3 away from 4, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 3

Going ahead to step 6:
When dividing 12 by 3, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 82914.0
The remainder is 0 after subtracting 12 from 12.
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 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 82914.0
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.

Going ahead to step 8:
When dividing 0 by 3, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 82914.0
Subtract 0 from 0 to 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.

The final result is 82914.0 with a remainder of 0.0.
