Can all the steps of applying for a patent be completed online?

Generally not. You need to open an account with paper in the National Information Bureau first, and then you can apply electronically and pay the bill electronically. However, it should be noted that because patent application is a special category, people who don't know much about doorways may need to spend a lot of time and investment, and may not be able to successfully complete the patent application work. Once overpaid, the National Information Bureau will not refund the fee. So we need to find a special agent to complete the work.
