OK, let's crack this. We're given 217 and our task is to multiply it by 39. Essentially, we'll be adding 217 to itself 39 times.
Step 1: 0 + 217 = 217
Step 2: 217 + 217 = 434
Step 3: 434 + 217 = 651
Step 4: 651 + 217 = 868
Step 5: 868 + 217 = 1085
Step 6: 1085 + 217 = 1302
Step 7: 1302 + 217 = 1519
Step 8: 1519 + 217 = 1736
Step 9: 1736 + 217 = 1953
Step 10: 1953 + 217 = 2170
Step 11: 2170 + 217 = 2387
Step 12: 2387 + 217 = 2604
Step 13: 2604 + 217 = 2821
Step 14: 2821 + 217 = 3038
Step 15: 3038 + 217 = 3255
Step 16: 3255 + 217 = 3472
Step 17: 3472 + 217 = 3689
Step 18: 3689 + 217 = 3906
Step 19: 3906 + 217 = 4123
Step 20: 4123 + 217 = 4340
Step 21: 4340 + 217 = 4557
Step 22: 4557 + 217 = 4774
Step 23: 4774 + 217 = 4991
Step 24: 4991 + 217 = 5208
Step 25: 5208 + 217 = 5425
Step 26: 5425 + 217 = 5642
Step 27: 5642 + 217 = 5859
Step 28: 5859 + 217 = 6076
Step 29: 6076 + 217 = 6293
Step 30: 6293 + 217 = 6510
Step 31: 6510 + 217 = 6727
Step 32: 6727 + 217 = 6944
Step 33: 6944 + 217 = 7161
Step 34: 7161 + 217 = 7378
Step 35: 7378 + 217 = 7595
Step 36: 7595 + 217 = 7812
Step 37: 7812 + 217 = 8029
Step 38: 8029 + 217 = 8246
Step 39: 8246 + 217 = 8463

So, 217*39 = 8463
