∞ is not a number. You cannot divide 1 by it.
Besides, if 1/∞=0, then you could multiple both sides by ∞ and get:
1(∞)/∞ = 0(∞)
...which gives...
∞/∞ = 0
...which means...
1 = 0
No.

Generally, in my classes at least, it is taken as 0.
I believe you are thinking of the graph y = 1/x, where the y value tends towards zero as the value of x tends towards ∞. However, the value of y never becomes equal to 0, nor does the value of x become equal to ∞.
He tells us that when it so close to zero, we should just write it as zero.
