Step 1: 0 + 677 = 677
Step 2: 677 + 677 = 1354
Step 3: 1354 + 677 = 2031
Step 4: 2031 + 677 = 2708
Step 5: 2708 + 677 = 3385
Step 6: 3385 + 677 = 4062
Step 7: 4062 + 677 = 4739
Step 8: 4739 + 677 = 5416
Step 9: 5416 + 677 = 6093
Step 10: 6093 + 677 = 6770
Step 11: 6770 + 677 = 7447
Step 12: 7447 + 677 = 8124
Step 13: 8124 + 677 = 8801
Step 14: 8801 + 677 = 9478
Step 15: 9478 + 677 = 10155
Step 16: 10155 + 677 = 10832
Step 17: 10832 + 677 = 11509
Step 18: 11509 + 677 = 12186
Step 19: 12186 + 677 = 12863
Step 20: 12863 + 677 = 13540
Step 21: 13540 + 677 = 14217
Step 22: 14217 + 677 = 14894
Step 23: 14894 + 677 = 15571
Step 24: 15571 + 677 = 16248
Step 25: 16248 + 677 = 16925
Step 26: 16925 + 677 = 17602
Step 27: 17602 + 677 = 18279
Step 28: 18279 + 677 = 18956
Step 29: 18956 + 677 = 19633
Step 30: 19633 + 677 = 20310
Step 31: 20310 + 677 = 20987
Step 32: 20987 + 677 = 21664
Step 33: 21664 + 677 = 22341
Step 34: 22341 + 677 = 23018
Step 35: 23018 + 677 = 23695
Step 36: 23695 + 677 = 24372
Step 37: 24372 + 677 = 25049

So, 677*37 = 25049
