Mike, you need to set the 15deg first in Options > General > Angle constraint.
You can use the drop down or type in whole numbers.

1. Select object
2. Set Centre of rotation
3. Hold Ctrl key down
4. Left drag object to its next stop position.
5. Right-click
6. Repeat round the clock

You will always get 90deg stops regardless, I believe.
