Haskell has no problem with this(though its default Num hierarchy is sorely lacking)

    Prelude> a = 1
    Prelude> a/2
    0.5
    Prelude> :t a/2
    a/2 :: Fractional a => a
    Prelude> b = 1 :: Int
    Prelude> b/2

    <interactive>:6:1: error:
        • No instance for (Fractional Int) arising from a use of ‘/’
        • In the expression: b / 2
          In an equation for ‘it’: it = b / 2
    Prelude> b `div` 2
    0
    Prelude> :t div
    div :: Integral a => a -> a -> a
