Just as before, align the dozuki blade to the edge of the workpiece and make a couple of preliminary cuts to ensure you're on the right path.

Keep cutting into the workpiece until the notch is created.

That's how you create a notch in your workpiece using a dozuki. If all went according to plan, all its teeth should still be intact, and you should have a rectangular section of wood missing from the workpiece.

Remember: the dozuki blades are replaceable. There's no reason to throw away a dozuki if the teeth snap off. In fact, you can grind them off and use the old blade as a scraper! (Thanks Mr. WoodMan!)
