Generally speaking, you simply:

1) enable contrib and non-free in sources.list

2) apt-get update

3) figure out which firmware package is needed, and install it

For your case of kbl_dmc_ver1_04.bin I can just look at my own
computer:

unicorn:~$ dpkg -S kbl_dmc_ver1_04.bin
firmware-misc-nonfree: /lib/firmware/i915/kbl_dmc_ver1_04.bin

So, step 3 for you would be "apt-get install firmware-misc-nonfree".
In the general case, you can use apt-file or https://packages.debian.org/
to find the package name for a given firmware filename.
