Sure thing! We've got 819 and we're gonna multiply it by 8. That's the same as adding 819 to itself 8 times.
Step 1: 0 + 819 = 819
Step 2: 819 + 819 = 1638
Step 3: 1638 + 819 = 2457
Step 4: 2457 + 819 = 3276
Step 5: 3276 + 819 = 4095
Step 6: 4095 + 819 = 4914
Step 7: 4914 + 819 = 5733
Step 8: 5733 + 819 = 6552

So, 819*8 = 6552
