elementary set theory - construct a bijection between (0,1) to R/N

Suppose A=(0,1) and B=R/N. Then how to construct a bijection from A to B? i am aware of bijections from (0,1) to R. a hint would be helpful here. where R are real numbers and N are natural numbers and R/N is the set of reals without natural numbers
