“steps” to asking someone out?

Im 19M and in college. I will preface with the fact im very shy and hardly ever talk to new people and i think i might come off as cold when i do but i want to change that. Ive been on one date and it went ok but it was through a dating app and honestly i have not had much of any luck with them besides that. I want to ask people out in real life as i feel like that would be more effective. I dont get how to do this though. How exactly do you get to seeing someone who is beautiful to asking them on a date? Do you talk to them first or just ask them out? If so how long do you talk to them? How do you make it clear you are not just being friendly? Do you ask for their number? When do you do this? This sounds kinda dumb but could someone tell me step by step the way, or the best way i suppose, things should progress, i have so many questions, lol. Id love to have a gf but this lack of knowledge is holding me back.
