Can anyone help me? I'm trying to find the remainder when 111111222222 is divided by 7 without using any long division.(adsbygoogle = window.adsbygoogle || []).push({});

I thinking that i can take the alternating sums of the 3 digits blocks and set that mod7. I'm not sure if i'm on the right track or not.

thanks
