title: Calculate how many times a static number fits into another number
body: <p>For a surface calculation I am searching for the following solution.</p>
  
  <p>I have a size of the surface like 60m², for this square I have 2 kind of
  materials sizes. Material size of 2m² and 4m². The challenge for me now is
  to calculate the needed materials efficiently as possible and keep a rest
  of the material to the minimum.</p>
  
  <p>So, filling a surface of 60m² with most as possible with 4m² materials and fill it up with 2m2 to keep material to the minimum.</p>
