I was wondering where I can try to code assembly. I want to code a x86 processor, but I am not sure where I should do so. Can I do it in visual studio? Is there a program in which I can code assembly?
I Googled it and looked for it everywhere but I couldn't find anything.
When I started using assembly I was using Turbo Assembler (TASM) under DosBox emulator. There are great variety of videos and blog posts over Internet on how to setup and use it. It is really easy. It has all the needed tooling - compiler and debugger. So give it a chance. You can use each text editor you prefer for writing the source.
It is possible to use MS VS but it has some specifics. I recommend you to start with TASM.
Good luck!
