OK, let's crack this. We're given 619 and our task is to multiply it by 29. Essentially, we'll be adding 619 to itself 29 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
Step 10: 5571 + 619 = 6190
Step 11: 6190 + 619 = 6809
Step 12: 6809 + 619 = 7428
Step 13: 7428 + 619 = 8047
Step 14: 8047 + 619 = 8666
Step 15: 8666 + 619 = 9285
Step 16: 9285 + 619 = 9904
Step 17: 9904 + 619 = 10523
Step 18: 10523 + 619 = 11142
Step 19: 11142 + 619 = 11761
Step 20: 11761 + 619 = 12380
Step 21: 12380 + 619 = 12999
Step 22: 12999 + 619 = 13618
Step 23: 13618 + 619 = 14237
Step 24: 14237 + 619 = 14856
Step 25: 14856 + 619 = 15475
Step 26: 15475 + 619 = 16094
Step 27: 16094 + 619 = 16713
Step 28: 16713 + 619 = 17332
Step 29: 17332 + 619 = 17951

So, 619*29 = 17951
