Step 1: 0 + 156 = 156
Step 2: 156 + 156 = 312
Step 3: 312 + 156 = 468
Step 4: 468 + 156 = 624
Step 5: 624 + 156 = 780
Step 6: 780 + 156 = 936
Step 7: 936 + 156 = 1092
Step 8: 1092 + 156 = 1248
Step 9: 1248 + 156 = 1404
Step 10: 1404 + 156 = 1560
Step 11: 1560 + 156 = 1716
Step 12: 1716 + 156 = 1872
Step 13: 1872 + 156 = 2028
Step 14: 2028 + 156 = 2184
Step 15: 2184 + 156 = 2340
Step 16: 2340 + 156 = 2496
Step 17: 2496 + 156 = 2652
Step 18: 2652 + 156 = 2808
Step 19: 2808 + 156 = 2964
Step 20: 2964 + 156 = 3120
Step 21: 3120 + 156 = 3276
Step 22: 3276 + 156 = 3432
Step 23: 3432 + 156 = 3588
Step 24: 3588 + 156 = 3744
Step 25: 3744 + 156 = 3900
Step 26: 3900 + 156 = 4056
Step 27: 4056 + 156 = 4212
Step 28: 4212 + 156 = 4368
Step 29: 4368 + 156 = 4524
Step 30: 4524 + 156 = 4680
Step 31: 4680 + 156 = 4836
Step 32: 4836 + 156 = 4992
Step 33: 4992 + 156 = 5148
Step 34: 5148 + 156 = 5304
Step 35: 5304 + 156 = 5460
Step 36: 5460 + 156 = 5616
Step 37: 5616 + 156 = 5772
Step 38: 5772 + 156 = 5928
Step 39: 5928 + 156 = 6084

So, 156*39 = 6084
