First make a single circle then an extruded cut. Next turn on Temporary Axis and use that for your linear pattern (see first screenshot).
Next use a circular pattern and use the the Temporary Axis for the axis of the pattern. For the angle change it from 360 to whatever you need and pick 3 for the quantity and this will split the outer two (see second screenshot).
Note: You could use multiple circles on the first sketch, but if they are spaced evenly it's cleaner to make a single circle and linear pattern it.
