Let's roll up our sleeves and solve this. We have 619 and we're going to multiply it by 9, essentially adding 619 to itself 9 times.
Step 1: 0 + 619 = 619
Step 2: 619 + 619 = 1238
Step 3: 1238 + 619 = 1857
Step 4: 1857 + 619 = 2476
Step 5: 2476 + 619 = 3095
Step 6: 3095 + 619 = 3714
Step 7: 3714 + 619 = 4333
Step 8: 4333 + 619 = 4952
Step 9: 4952 + 619 = 5571

So, 619*9 = 5571
