you cant divide by 0 because anything divided by 0 is infinite.
limit 1/n as n approaches 0 is infinite, so the limit does not exist, so you cannot divide by 0.
0/0 is undefined because division is defined to be the inverse of multiplication. a*b = c : c/b = a... well when you have c = 0, b = 0 so you get 0/0 = a, if you plug that into the first equation you get a*0 = 0, and a could be any value so it does not exist.
