Im sorry but 90% that no one here understands that language. And please make a CLEAR statement what is the problem. I cannot conclude from the picture whats going on, and even if I could, you still should have typed in the problem.

Its the least you can do if you are already asking for help, giving a clear statement what seems to be a problem.

I calculated the quiescent point for your transistor. It should be ok, my simulations confirmed this somewhat.

In first 2 steps what I did is I split the voltage divider into 2 sources powering transistor on their own. This doesn't change anything in problem.

Also I flipped the picture. So emitter is bottom now.

You are asking Vc, Vb, Ve. I think you should have this basic knowledge of figuring out these parameters from these results.
