One way to do it is to do the division in base 10, then convert the answer to base 5:
1423/24 (base 5) = (base 10) = (base 10)
17 (base 10) =
You can do the division in base 5; you just need to know how to do addition and subtraction in base 5.
Since you are not familiar with base 5, it helps to start by making a list of the multiples of 24 in base 5. Of course the work must be done in base 5; you can use either addition or multiplication to make the list. As a check of your work, you can show that in base 5 "24" times "5" is "240".
Now you have a list of all the multiples, in base 5, of the divisor, 24. Do the long division just as in base 10, remembering that the subtractions are in base 5.
