.I find the steering of the cars almost impossible

I am a beginner using xbox one.I also started using forza 6.I find the steering of the cars almost impossible.
I hear lots of people talk about changing the dead zones to improve the steering.I have never been in the top 3.
Can anybody tell me as a beginner how I can improve my steering using the controller.Are there any video clips
on the best way to improve my steering.Also how can I access the deadzones using my xbox and controller.Please give me clear instructions using my controller
on how to access these.When I play forza 6 I can not see an option for this.What do I need to do to access these.I see alot of videoes of drivers changing the settings.
But what I don’t see is the driver explicitly showing you how to access these when playing Forza 6.

Thank you
