That's "divide", not "device".
Not sure it's the solution that the professor had in mind, but you
can use exponentiation (in Perl written as **,
5**2=25,5**3=125,...).
It's enough to remember that
x ** -1 = 1 / x
and the rest is trivial.
Another option would be to use a numerical solution. Guess the
result, see whether it's too big or too small, change the guess
accordingly, check again and continue like this until the error is
small enough.
