         var n = 5;
         var  i = 1;
         var rem = 0;
         var binary = 0;

    while (n!=0) 
     {
       rem= n % 2;
       n= n / 2;

After division converts it to integer otherwise it may lead to infinite loop since it won't reaches 0 in some case(number may contain decimal part).

n= parseInt(n / 2, 10);

The problem here is

 n = n / 2;

because in JavaScript (jQuery) the division returns a float number, not an integer.

So you have first 2.5, then 1.25, 0.625, 0.3125, and so on, so your condition is not satisfied.

To avoid this you just need to parse to integer the float result

n = parseInt(n / 2);
