OK Bctoscano. So first you have to take out the biggest number you can take out, so that would be 910, so 910 divided by 7 is 130 because 700 divided by 7 is 100 and 210 divided by 7 is 30. Now what you have left is 38. The biggest amount I could take out is 35 so, 35 divided by 7 is 5. Now we have 3 left so the answer is 130 + 5 r.3 so 135 r.3.
