Uncaught DivisionByZeroError: Division by zero Error in PHP

I’m trying to do an Calculation of my Project
were I need to do Division and Multiplication to get my Ans
but getting an error "Uncaught DivisionByZeroError: Division by zero".
my Code and Error as shown in Screenshots

        $total_plates=$row['s_tps'];
    $total_a_kg=$row['s_kg'];
    $plates_per_kg=$row['s_pkg'];
    $remaing_kg=(1000/$plates_per_kg)*$total_plates;
    echo "$remaing_kg";[![enter image description here][1]][1]

>Solution :

In the following line,

$remaing_kg=(1000/$plates_per_kg)*$total_plates;

if ‘$plates_per_kg’ value is 0, then this error will occur

Or "0", or null, or false, or array() or anything that intval would return 0 for.

Edit: Thanks for the comment @msbit
