What are the processes to become a cardiac surgeon?

I am currently a high school freshman. I love science and math. I want to be a cardiac surgeon when I am 30s. I have done a lot of research based on the way to become a cardiac surgeon. However, I need someone who can organizes and retells the whole processes to become a cardiac surgeon. Can someone please explain me the processes step by step? Please include the following: Requirement for the medical school(generally)? MCAT? Medical School's Curriculum and Exams? USMLE(all three parts. I especially get confused by this exam) Residency? Internship? Fellowship? I will thank you so much if you would like to answer my questions.
