Let's roll up our sleeves and solve this. We have 656 and we're going to multiply it by 8, essentially adding 656 to itself 8 times.
Step 1: 0 + 656 = 656
Step 2: 656 + 656 = 1312
Step 3: 1312 + 656 = 1968
Step 4: 1968 + 656 = 2624
Step 5: 2624 + 656 = 3280
Step 6: 3280 + 656 = 3936
Step 7: 3936 + 656 = 4592
Step 8: 4592 + 656 = 5248

So, 656*8 = 5248
