Let's roll up our sleeves and solve this. We have 186 and we're going to multiply it by 39, essentially adding 186 to itself 39 times.
Step 1: 0 + 186 = 186
Step 2: 186 + 186 = 372
Step 3: 372 + 186 = 558
Step 4: 558 + 186 = 744
Step 5: 744 + 186 = 930
Step 6: 930 + 186 = 1116
Step 7: 1116 + 186 = 1302
Step 8: 1302 + 186 = 1488
Step 9: 1488 + 186 = 1674
Step 10: 1674 + 186 = 1860
Step 11: 1860 + 186 = 2046
Step 12: 2046 + 186 = 2232
Step 13: 2232 + 186 = 2418
Step 14: 2418 + 186 = 2604
Step 15: 2604 + 186 = 2790
Step 16: 2790 + 186 = 2976
Step 17: 2976 + 186 = 3162
Step 18: 3162 + 186 = 3348
Step 19: 3348 + 186 = 3534
Step 20: 3534 + 186 = 3720
Step 21: 3720 + 186 = 3906
Step 22: 3906 + 186 = 4092
Step 23: 4092 + 186 = 4278
Step 24: 4278 + 186 = 4464
Step 25: 4464 + 186 = 4650
Step 26: 4650 + 186 = 4836
Step 27: 4836 + 186 = 5022
Step 28: 5022 + 186 = 5208
Step 29: 5208 + 186 = 5394
Step 30: 5394 + 186 = 5580
Step 31: 5580 + 186 = 5766
Step 32: 5766 + 186 = 5952
Step 33: 5952 + 186 = 6138
Step 34: 6138 + 186 = 6324
Step 35: 6324 + 186 = 6510
Step 36: 6510 + 186 = 6696
Step 37: 6696 + 186 = 6882
Step 38: 6882 + 186 = 7068
Step 39: 7068 + 186 = 7254

So, 186*39 = 7254
