Register new business

Hello Guys,
I have been working in a Digital Agency for 2 years, Due to the current pandemic situation across the globe, I am working from home
and now, I was thinking of changing my pace in my career and decided to set up an own office business for a digital agency in my hometown, I searched online on how to register a new business online and came across a couple of registrations of websites. Every website has different procedures, and it is very much confusing. I would really appreciate it if anybody could help me by advising me on the above.

Waiting for your positive reply
Thank You.
