Solving Approach

How do you plan to solve it?

Code

module safe_div8 (
    input  [7:0] dividend,
    input  [7:0] divisor,
    output [7:0] q,
    output [7:0] r,
    output       div_by_zero
);

    assign div_by_zero=(divisor==8'b0);

    assign q  = divisor==8'b0 ? 8'b0 :dividend/divisor;
    assign r =  divisor==8'b0 ? 8'b0 :dividend%divisor;

endmodule
