Proof step 3 from proof bits2bytes-rec-01 (previous step)

bits = firstn(# bits % 8, bits) + restn(# bits % 8, bits), 8 < # bits ⊦ # bits % 8 = 0, bits2bytes(bits) = bits2bytes(firstn(# bits % 8, bits)) + bits2bytes(restn(# bits % 8, bits)), bits = []

User applied rule insert equation

And obtained the following new goals

Proof step 4:
8 < # bits ⊦ # bits % 8 = 0, bits2bytes(firstn(# bits % 8, bits) + restn(# bits % 8, bits)) = bits2bytes(firstn(# bits % 8, bits)) + bits2bytes(restn(# bits % 8, bits)), bits = []
