Let's roll up our sleeves and solve this. We have 865 and we're going to multiply it by 8, essentially adding 865 to itself 8 times.
Step 1: 0 + 865 = 865
Step 2: 865 + 865 = 1730
Step 3: 1730 + 865 = 2595
Step 4: 2595 + 865 = 3460
Step 5: 3460 + 865 = 4325
Step 6: 4325 + 865 = 5190
Step 7: 5190 + 865 = 6055
Step 8: 6055 + 865 = 6920

So, 865*8 = 6920
