Should I use a resistor voltage divider or dedicated voltage IC?
Using a resistor voltage divider network or a dedicated regulator IC to power a Chip, which one is better and more efficient, why ?

I would say use a regulator IC because getting the desired current rating for your design won't be difficult for you to find out, the are various IC with specific current rating that will suit your design. And they are cost effective also.

Planning on using a voltage divider because it will save cost, which is more reasonable to use and why. @pallavaggarwal @Petr Dvořák
Long story short. Use numbers that fit your design.
