43. Guard Division by Zero

How do you plan to solve it?

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

    always @(*) begin
        // default values (avoid latch)
        q = 8'd0;
        r = 8'd0;
        div_by_zero = 1'b0;

        if (divisor == 8'd0) begin
            div_by_zero = 1'b1;
            // q and r remain 0
        end
        else begin
            q = dividend / divisor;
            r = dividend % divisor;
        end
    end
