I'm not sure what the numeric extension has to do with division of channels?

When you say "division of pixel" do you mean the division of all
channels in a pixel?

you can do that like this:

    typedef rgb8_pixel_t pixel_t;

    pixel_t a( 10, 20, 30 );
    pixel_t b( 10, 20, 30 );

    static_for_each( a, b, [] ( channel_type< pixel_t >::type& a
                              , const channel_type< pixel_t >::type& b
                              )
        {
            a /= b;
        } );

Hope that helps,
Christian
