If you mean to send it to ResearchGate: This is not a publisher, papers cannot be published here. You have to find a journal corresponding to the topic of your paper. ResearchGate is for sharing published and unpublished research with the community. See https://explore.researchgate.net/display/support/Getting+started for further explanations.
A very interesting question. my question is if you want to publish it (any journal)does this mean you did not follow any guidelines at all? Maybe, it would be best to see the guidelines and the APCs (it is a document or several under publishing,normally on any menu).Is it free access/licence?. If anyone has a better,please come and share it.
