Putting parentheses around expressions involving a mixture of
multiplicative and additive operators might sometimes be a cunning
idea...   :-}   Otherwise
   (591125662431::Int) `div` (517::Int)
is correctly converted into
   (567659506 + (275 * 2147483647)) `div`  517
but
    591125662431       `div` (517::Int)
turns into the messed up
    567659506 + ((275 * 2147483647) `div`  517)
