What is the correct first step in finding the area of the base of a cylinder with a volume of 140 pi cubic meters and a height of 12 meters

The volume of the cylinder by definition is given by:
 V = Ab * h
 Where,
 Ab: base area
 h: height
 Substituting values we have:
 140 = Ab * 12
 To find the area, the first step is:
 Pass the 12 dividing.
