If you want to find accurate multiple values of 0.25, you could divide the values from highlighted cell by 0.25 and if you find no decimal value that would be the accurate multiple of 0.25, e.g. 1.00/0.25 = 4 accurate time, 3.26/0.25=13.04 not accurate. Note: this is as per my understanding of your query.
