How do I split a random value into an array of characters?

I'm trying generate random lat and lng positions and I want to use this false data with javascript and put it in a p with different span

//  latitude

var latMin = parseInt(-90);
var latMax = parseInt(90);
var latAnswer = document.getElementById("latitude");
var lat = Math.floor(Math.random() * (latMax - latMin + 1) + latMin);
var latSplit = lat.split('');

console.log(latSplit);
console.log('lat:'+lat);

$( latSplit ).insertAfter( '#latAfter' );

//  longitude

var lngMin = parseInt(-180);
var lngMax = parseInt(180);
var lngAnswer = document.getElementById("longitude");
var lng = Math.floor(Math.random() * (lngMax - lngMin + 1) + lngMin);
var lngSplit = lng.split('');

console.log(lngSplit);
console.log('lng:'+lng);

$( lngSplit ).insertAfter( '#lngAfter' );

And then, in my result, I wanna have something like that <span>3</span><span>8</span><span>.</span><span class="end">7</span> then I want to split in different div with a class in the last
