Here we go, This is basically what I did on Balloon wires previously. Still my first take was not that great 
(this picture expose my laziness while doing railings ops).
So don’t do this on edit mode 
My way to adding objects is moving 3D cursor there where I want my mesh to be. then I scaled the first step between railings with raw math (I have my loyal TI-84 calculator always on my desk.)
End result is, well, stairs on the monkey god’s temple.
