@AliSajad you get downvoted because it seems like there was no effort to solve it by yourself nor to use the search. — pdu, Apr 16 '13 at 07:00

var c_formatted = c.toFixed(2);
console.log(c_formatted); // 19.30

As @Barmar suggested, i would also suggest the same. but make sure that the toFixed() will return a string not a number, so that we have to cast it manually either by inserting + operator in the beginning or by using Number() function.

var a =20;
var b=386;
var c= +(b/a).toFixed(2);
