Alignment Issue – Blog Posts and Blog Homepage will not align right

I have an aside aligned to the left for my sidebar, but I’m having a really hard time trying to align the rest of my content to the right for my blog homepage and the individual blog posts. Everything is aligning correctly for my home page. However, my blog posts continue to sit above my sidebar. I’m not sure if I am adding div tags in the wrong spots or not. I have yet to apply my theme to my actual website as I have only been working locally. Please help!
