For loop in 15 min increments

Hi I am trying to run a for loop to generate a List<String>  for a dropdown list that will allow users to select a time value based on 15 min increments
.25, .50, .75, 1.0, 1.25   etc...

this is what I have so far but it keeps returning "0" 's

protected List<String> fill_ddlDuriation()
        {
            List<String> lstDuration = new List<String>();
            for(int i = 0; i < 720; i += 15)
            {
                i = i / 60;
                lstDuration.Add(i.ToString());
            }
                return lstDuration;
        }

You could also use linq:
using System;
using System.Linq;
using System.Collections.Generic;

namespace EE_Q28570067
{
	class Program
	{
		private readonly static List<double> durations = new List<double>();

		static void Main(string[] args)
		{
			durations.AddRange((from i in Enumerable.Range(0, 720) where i % 15 == 0 select ((double)i / 60f)));
			foreach (var duration in durations)
				Console.WriteLine(string.Format("Interval: {0}", duration));
			Console.ReadLine();
		}
	}
}

Hi below was my solution, thanks to all for your feedback, not very familiar with linq syntax it_saige, but thanks for your input.

protected List<String> fill_ddlDuriation()
        {
            List<String> lstDuration = new List<String>();
            for(int i = 15; i < 735; i += 15)
            {
                Decimal minResult = (i*100) / 60;
                minResult = Math.Truncate(minResult) / 100;    
                lstDuration.Add(minResult.ToString("F"));
            }
                return lstDuration;
        }
