It's been awhile since I played... but...
Excuse the mess but you should get the general idea.
Start out with a basic beat, 4/4 count, bass, snare, bass, snare, etc...
Get that beat down, it trains your foot and hand to work in unison. Count in your head, 1, 2, 3, 4... for every number hit the bass, then the snare, then bass, snare, etc...
Practice this till you feel comfortable with it.
Then move on to the second half of my drawing

same beat, still 4/4 count, however we add the hi hat part, slightly faster than the rest of the beat, by 1/2 .
so
Once you get that beat, you can vary the beat from there.... Once you get this beat down, you're pretty much set...
Remember, if it doesn't sound right, it probably sucks
