The easiest way would be to say 117 billion is ~2^37 because 2^[7, 10, 20] are 128, 1024, and about a million (1024*1024), so multiplying those all together gives a little over 128 billion, which is pretty close to 117 billion. So, 2^42/2^37=2^5=32. Pretty close, all mental math. Granted, it does require you to either memorize or compute powers of 2 up to 10.
