I highly recommend reading up some literature upon the post sound process, especially John Purcell's Dialogue book and Dave Yewdall's as well. I say all of this because I took at look at the questions you have asked on SSD, and all 3 seem to be considerably related/reformulated and all are quite rudimentary 'bread-and-butter' topics of post sound.
This is not to say you are invalid in asking the question. I share this because the questions you pose are so open-ended that providing a succinct response is difficult if not impossible - the workflow is so vast and the nuances so detailed (even on a show-by-show basis). So you likely will not find the perfect response you are seeking from the community because of the broadness of the question(s).
Gaining an overall understanding of the post process through those two books, as well as others that people may be able to recommend (I believe such a question about literature was actually asked on here not too long ago, you may have to search for it) will likely be a beneficial starting point.
Again, I say this not to deter you nor your question, just as a hopefully helping hand in guiding you to where you will likely find the most fulfilling answer, to which SSD can be a great resource thereafter with more of the details and idiosyncrasies of the post process.
