Kingroot isn't that good.
Use Towelroot, it is one click and takes less than 5 seconds. Go to xda-developers.com and look up your device. It is a forums dedicated to mobile devices. It will have information about root, ROMs, recoveries, etc. I must warn you that thanks to Samsung and Knox, it may be impossible for Root or ROMs
