CREATION OF A STAIRWAY with Array and Bevel modifier With the default cube selected edit it in “Edit” mode using the 3D manipulator. We form a step.
If the center (Origin) of the object to become bad we can re-center it with the “Origin” of the toolbox in “Object” and selecting “Geometry to Origin” in the menu that appears. Then we add a modifier “Array” in the properties panel “Modifiers”. We click Add and select the Array Modifier.
With the slider “Count” select the number of steps you want. And with sliders “Relative Offset” adjust the distance between them.

And if you want the bevel is applied only to certain edges can select “Weight” and “Average”, then we have to enter “Edit” mode and in the toolbox (“T”) all the way down to “Mesh Options “we have select” Tag Bevel “in the blind” Edge Tag Mode “.

With the 3d manipulator move mode: define the separation between steps (also can press the letter “G”).
In rotate mode: define rotation between steps. (You can also press “R” key).
