This year they didn't bloom at all period. What did I do wrong. When you divided your daffodils, in all likelihood you replanted them at too shallow a depth. Daffodils need to be planted deeply to blossom well, otherwise they produce great, healthy leaves, but no flowers. When the leaves have browned and died down, replant them to a depth of at least three times the size of the bulb which should allow for a minimum of three inches of soil on top of the bulb.
Some growers recommend even deeper planting of up to five times the size of the bulb.
