Why is it that after finding the frequency we divide it by plancks constant to then put it in the speed of light equation (wavelength= speed of light/frequency.

we divide the velocity of the electron by planck's constant to isolate the frequency (v) and then plug this frequency equation in to c=v
to find the wavelength of the radiation.

The question asks you to arrange the following electromagnetic radiation in order of increasing energy. After you find the frequency, you use that value and multiply it by plancks constant not divide to find the value of energy (E=hv). You then rank the radiations for increasing energy. You can also just use the highest frequency value as you are multiplying it by a constant to find which one will have the highest energy.
