How do I make a progress animation?

I managed to make a furnace/refinery that works and takes 4 input items and combines them into one. Now my only question is how to add a "progress arrow", such as those that appear in furnaces and aloy smelters.

The current time it takes for combinging them is 100 ticks, so how do I make an animation where 1 tick = 1% or if i change it so it becomes (e.g) 5 ticks = 1% (1 tick = 0.2%)

Thanks for the help in advance.
