Let's get this math done. We have 809 and we're going to multiply it by 6. This is the same as taking 809 and adding it to itself 6 times.
Step 1: 0 + 809 = 809
Step 2: 809 + 809 = 1618
Step 3: 1618 + 809 = 2427
Step 4: 2427 + 809 = 3236
Step 5: 3236 + 809 = 4045
Step 6: 4045 + 809 = 4854

So, 809*6 = 4854
