Is this not a repeat of the left and right output justification as on the previous thread in Richard's link.

7040 left justified is 110 right justified using Henrik's 4.88mV then

110*4.88/1000=0.5368 V

Or put another way 7040/64=110 which shifts the 10 bit left justified result 6 bits to the right making the result the same as a right justified result.
