Finally, I reread my story at least once, usually twice and find additional errors or little make tweeks to make the story better.
It always helps to use multiple spellcheckers (I often relied on some I accessed via my old website via plug-ins), as each picks up different thinks. However, you need to keep a skeptical view of their 'suggestions', as often they'll either be flat out wrong, or won't fit the circumstances.
Another use I've found for Google is to use Google's lookup feature, where the search engine attempts to guess what word you're trying to spell. I can't spell my way out of a paper bag, and when young, I found dictionaries useless, because if you can't spell the first part of a word, there's no hope of ever finding the word in the dictionary to figure out how to spell it, but now I use the Google lookup feature frequently both while I'm writing my first draft, and again whenever I revise my stories.
Finally, having the story read aloud to you helps, especially in improving the story's pacing, but also in determining what's mere bloat (unnecessary words and phrases), plus you'll pick up the homonyms you'd ordinarily never notice. There are multiple apps online that'll read your story outlaid to you. Word performs this task too, though I've never been fond of their reader, preferring the default Mac 'read aloud' tool.
