Well, this is not IO, but:

public struct DivInt
{   public int quot;
     public int rem;
}

public static class Utility
{   public static DivInt Div(this int dividee, int divisor)
     {   int quot;
         int rem;
         quot = Math.DivRem(dividee, divisor, out rem);

         //always round down
         if(rem < 0)
         {   quot--;
             rem += divisor;
         }
         return new DivInt{quot = quot, rem = rem};
     }
}

Could be used in some way like:
     int quotient;
     int remainder;
     if (true)
     {   var divResult = (x + y).Div(ASlowFunction());
         quotient = divResult.quot;
         remainder = divResult.rem;
     }


If you say it sucks that one has to declare an utility class just 
to be nominally object-oriented, I agree.
