how can i avoid error Division by zero laravel?

this is my function

$total = Reservation::count();

        $newreservations = Reservation::where('status','=','Pending')->count();
        $newreservationsperc = $newreservations / $total * 100;

        $acceptedreservations = Reservation::where('status','=','Accepté')->count();
        $acceptedreservationsperc = $acceptedreservations / $total * 100;

        $Refusedreservations = Reservation::where('status','=','Refusé')->count();
        $Refusedreservationsperc = $Refusedreservations / $total * 100;
        return  view('admin.dashboard',compact('hotels','reservations','clients','messages','newreservationsperc','acceptedreservationsperc','Refusedreservationsperc','newreservations','acceptedreservations','Refusedreservations'));

when the $total is not 0 its working fine but when its null i got this error Division by zero i try this

`$total = Reservation::count();


    if($total != 0){
            $newreservations = Reservation::where('status','=','Pending')->count();
            $newreservationsperc = $newreservations / $total * 100;

            $acceptedreservations = Reservation::where('status','=','Accepté')->count();
            $acceptedreservationsperc = $acceptedreservations / $total * 100;

            $Refusedreservations = Reservation::where('status','=','Refusé')->count();
            $Refusedreservationsperc = $Refusedreservations / $total * 100;
            return  view('admin.dashboard',compact('hotels','reservations','clients','messages','newreservationsperc','acceptedreservationsperc','Refusedreservationsperc','newreservations','acceptedreservations','Refusedreservations'));

        }

            else
            return  view('admin.dashboard');`
