How to Get total and Current Slide Number of Carousel

Can you please let me know how I can get the total and current number of the carousel slides in bootstrap like the image below?

Image showing current page and total number of pages

I have an standard Bootstrap carousel and a <div> with the .num class to display the total and current number and I used this code to retrieve the numbers but it didn't go through

$('.num').html(){
  $('#myCarousel').carousel({number})
}

Thanks

Update:

Please find a sample at this jsfiddle LINK

Each slide has a .item class to it, you can get the total number of slides like this

var totalItems = $('.item').length;

Active slide has a class named as active, you can get the index of active slide like this

var currentIndex = $('div.active').index() + 1;

You can update these values by binding the bootstrap carousel slid event like this

$('#myCarousel').bind('slid', function() {
    currentIndex = $('div.active').index() + 1;
   $('.num').html(''+currentIndex+'/'+totalItems+'');
});

var totalItemsPop = $('#Mycarousel .item').length; 
$('#Mycarousel').on('slide.bs.carousel', function() {
       setTimeout(function(){ 
            currentIndexPop = $('#Mycarousel div.active').index() + 1;
            $('.num').html('' + currentIndexPop + '/' + totalItemsPop + '');
         }, 1000);
   });

after slide event, div will be active and can not get active index, so keep your code inside set time out function

Bootstrap 4 and js

  var totalItems = $('.item').length;
            var currentIndex = $('div.item.active').index() + 1;

            var down_index;
            $('.num').html(''+currentIndex+'/'+totalItems+'');

                $(".next").click(function(){
                currentIndex_active = $('div.item.active').index() + 2;
                if (totalItems >= currentIndex_active)
                {
                    down_index= $('div.item.active').index() + 2;
                    $('.num').html(''+currentIndex_active+'/'+totalItems+'');
                }
            });

                $(".prev").click(function(){

The only drawback with the below code will be that it doesn't show up till you go to next slide (triggers after each slide change).

JS/jQuery

$('#carousel-slide').on('slid.bs.carousel', function () {
  var carouselData = $(this).data('bs.carousel');
  var currentIndex = carouselData.getActiveIndex();
  var total = carouselData.$items.length;

  var text = (currentIndex + 1) + " of " + total;
  $('#carousel-index').text(text);
});

HTML 

<div id="carousel-index">
  <!-- Number will be added through JS over here -->
</div>

You can use jquery index() function to get the current index of active element inside list of item. So the code is look like this:

var currentItem = $("#carousel-1 .item.active" );
var currentIndex = $('#carousel-1 .item').index(currentItem) + 1;

Update of @Khawer Zeshan's code

For Bootstrap 3.0+ use slid.bs.carousel instead of slid and on instead of bind . So the update code will be like that

var totalItems = $('.item').length;
var currentIndex = $('div.active').index() + 1;

$('#myCarousel').on('slid.bs.carousel', function() {
    currentIndex = $('div.active').index() + 1;
   $('.num').html(''+currentIndex+'/'+totalItems+'');
});
