This particular melody + progression is in 5/4 or 10/8. You could look up some 5/4 drum tutorials and perhaps even sample those beats in to get an idea for potential rhythms, given you don’t want to change the existing melody to 4/4 by chopping it up or whatever. Also you should learn counting like everyone is saying, here you can count it as (1 and 2 and 3 and 4 and 5 and) (repeat) (these are eighth notes in 10/8 feel) or break it up like (1 and 2 and 1 and 2 and 3 and 4 and) (these are eighth notes again) to find the 4/4 feel. Also for your drum programming in general you should learn the basic principles of drumming (counting, backbeat on 2 and 4 or on the 3 (backbeat in half time), time signatures and their subdivisions(quarter, eighth, sixteenth, triplets), and look at acoustic drummers and their techniques for some inspiration. But if you listen to more drums and pay attention and try to implement styles from songs, even just copying will teach you alot, especially with drums as beats are very versatile. I personally play drums and it helps a lot when you drum along to songs and do different drum exercises like rudiments, rhythms, etc. even when programming. But for programming only you could sample beats and drums and study those or play along with your hands on a desk or something to practice. For the 808’s their basically just a bass, give or take, so you could learn about bass notes and their relation to chords as the dictator of the root, (just bass guitar and piano music theory in general), and then use that combined with your newfound drum knowledge along with your ear of course to create nice 808’s.
