1. Read and study as many books as you can about the publishing industry. There are many free books you can borrow from your local library! You can also get many on Amazon. You might also Google: "How to get a book published."
2. There are typically two (2) main ways to get your book published: The first is by submitting your manuscript to a traditional publishing company that publishes the type of books that you write. The second is by self publishing, which is very popular today. There are many small publishers and press companies that can support first time authors. One that I highly recommend is: https://www.westbowpress.com/en/why-westbow-press.

"God has put a dream inside you. It's yours, and no one else's. It declares your uniqueness. It holds your potential. Only you can birth it. Only you can live it. Not to discover it, take responsibility for it, and act upon it is to negatively affect yourself as well as all those who would benefit from your dream."
John C. Maxwell
Self-publishing is a possibility, but unless you're willing to put in a lot of marketing and public relations work, or pay someone else for it, you're likely not going to move a lot of copies. At least that's been my experience. (That said, there are some solid success stories in self publishing, mostly in genre categories like romance, fantasy, horror, etc.)
If you hope to get traditionally published, you'll probably need an agent first. A lot of publishing houses won't even look at manuscripts that don't come from agents. If you google literary agents, you'll get plenty of listings. Go through, see if any feel like a good fit, and submit your work to them according to their guidelines.
It helps if you've published shorter work or have a decent social following. Showing agents and publishers that you have some sort of existing audience makes you a less risky investment.
Also, write A LOT. And revise EVEN MORE. And be patient. It can take decades, as the saying goes, to become an overnight success.

It is exciting that you want to get your own book published, and there is some great advice available to you above in that regard.
My suggestion to you is to not wait for writing a whole book before you start looking at the options for getting published. Instead, I would recommend you submit shorter pieces for publication in local outlets such as weekly/monthly magazines, setting up your own blog where you can share your writing with the world to gain following, or monitoring global magazines such as The New Yorker, Boston Review, CRAFT etc. to experiment with the process of getting published and gain valuable feedback on your pieces.
I hope this helps!
If you want to try traditional trade publishing, and you don't have any personal contacts, you must first get past the gatekeepers. These are the people at literary agencies and publishing companies who read the "slush," which is the pile of unsolicited manuscripts that comes in the mail every day. I've had this job at a lit agency, two publishing companies, and two or three literary magazines, and my advice is to spend some time on your cover letter. Even if you have not been able to hire an editor to review your manuscript, make sure several people look at your cover letter. It should be brief, it should state the genre/audience you are targeting, and it should avoid too much personal detail (I can't tell you how many children's books I've seen that bragged "my children love this book!"—unfortunately, that's not super valuable).
Put some piece of information in your cover letter that will get your manuscript in front of somebody who will actually read it, although that person may not have any decision-making power when it comes to bidding for the contract. Note also that these slush reviewers usually only read 50 pages, but it's fine to send an excerpt from the middle of the book.
These are some things you can say (if they're true!) that will move your pages to the right pile:
