43. Guard Division by Zero

How do you plan to solve it?

module safe_div8 (
    input  [7:0] dividend,
    input  [7:0] divisor,
    output [7:0] q,
    output [7:0] r,
    output       div_by_zero
);
  assign q=(divisor)?(dividend/divisor):0;
  assign r=(divisor)?(dividend%divisor):0;
assign div_by_zero=(divisor)?0:1;
