=if(and(isnumber(A1),isnumber(A2),if(A1<0,A2/A1,0),0)
this checks if both are numbers and that the demonimator is not zero befor
dividing and if not will give a zero.

I have a number in cell A1, and in A2.
I need to divide A2 by A1 into A3 (that I can do)

I need A3 to be the answer in the form of a number or have it show a "0"

something like - If A3<1, "0", otherwise put the answer there.

I am not sure what you want but maybe something like
numerator in Cell A1
Denominator in Cell B1
=if(or(B1=0,b1=""),0,A1/B1)

the simple response to your question might also be
=A1/B1

how do I tell a formula to divide two cells, leave a "0" if that, and leave
the number is there is a number?
