Advice on ranking up?

Please do not just respond with something mean or ignorant

So I am trying to get some advice and help on what I can do better to rank up?

I know this is a broad topic , but it seems like every time I hit silver 3 that I get 3 or 4 games in a row where the team fights with each other and feeds and I end up losing and getting demoted. I hear this more than anything from the last pick " Mid or feed " Or something like this.

So since the community is going to be the community what can I do better to rank up? I am usually able to still get kills etc even with a feeding team . I ward and my positioning is overall pretty good I, I try to stay positive in games ( Would be a liar if I said I don't lose my cool sometimes with people fighting and feeding ) however in this community if you try to offer advice to players they often just say F* You! ......and they are all god.

I am not trying to say I am some Diamond god like player , but I would like to understand how people rank up without Duoing with a community so hell bent on getting mad and throwing or trolling.?

Anyway here are my stats http://www.lolking.net/summoner/na/19944898#profile

Again I am asking what can I do better to work around the stuff we cant control to rank up ?

Is ranking up about playing more than 1 or 2 games a day? ( That is all I really have time for ) Do you have to play the champions Riot makes OP to keep carrying? I also notice that I am always being paired with people who have a total of 5-10 ranked wins. is this riots way of Population control for lack of better terms? Thank you for your help , and taking the time to read my post.

Have a great day!
