First, write your story.
Edit your book several times to make it the best it can be, type it in proper manuscript form (visit
http://www.writersdigest.com to find out what is needed), consider joining a local writer's group to get feedback from other would-be writers, and get it proofread by someone who knows what they are doing (don't rely just on spellcheck). Edit it some more.
There are a tiny number of publishers that accept unsolicited manuscripts (those that don't go through a literary agent), so getting an agent first is a really good idea.
At the library or bookstore is Guide to Literary Agents, published by Writer's Digest, or Bowker's Literary Marketplace (or visit
http://www.agentquery.com). Look for agents that specialize in your genre, and are looking for new clients. Read, and follow, their submission guidelines. In those books will be something about writing a query letter, which is what you send to the agent, first. It's part synopsis of your book, and part explanation as to why your book deserves to be published. You have only that one-page letter to wow the agent, so take the time to make it a good one. Expect the whole process to take lots of time, and expect many rejections. When you are accepted by an agent, they will send your book to publishers, not you. The whole process is free, except for postage, until your book is bought by a publisher. That is when the agent gets their cut (usually 15%) of the money which would go to you.
If you decide to self-publish, then you will pay (potentially up to a couple of thousand dollars, depending on which publisher you choose).
Good luck!
