Examining binaries for firmware images I built when writing embedded software and for reverse engineering binaries by others to see how they work, make modifications. Fixing corrupted image files or figuring out how they work, examining Windows PE files or DLLs to get an overview of how they work. HxD for example can also do some limited calculations on the bytes as well as show you what CPU instruction they might represent. Sometimes a hex editor is useful for looking at data files stored as binary. I also used a hex editor extensively when dumping the output of streaming H264 NAL units to figure out why the video was corrupted.
