Adobe illustrator divide tool not working
I have a shape , i tried pen, line, or shapes , filling them in, or not, just strokes on them, i cant get divide to work. I am a beginner.
i was making this How to Design a Logo with Shadows in Illustrator - YouTube tutorial and i got stuck on the first divide with the pen tool 
After i use divide it creates this shape? and nothing happens after that, (no matter how many times i click divide) they arent grouped, i cant select individual parts, i cant paint individual parts , it just exists as 2 separate shapes and thats it, i opened another tab tried it with another shape and it worked, its something about this G that is making things hard.
