Step 5: 2496 + 624 = 3120
Step 6: 3120 + 624 = 3744
Step 7: 3744 + 624 = 4368
Step 8: 4368 + 624 = 4992
Step 9: 4992 + 624 = 5616
Step 10: 5616 + 624 = 6240
Step 11: 6240 + 624 = 6864
Step 12: 6864 + 624 = 7488
Step 13: 7488 + 624 = 8112
Step 14: 8112 + 624 = 8736
Step 15: 8736 + 624 = 9360
Step 16: 9360 + 624 = 9984
Step 17: 9984 + 624 = 10608
Step 18: 10608 + 624 = 11232
Step 19: 11232 + 624 = 11856
Step 20: 11856 + 624 = 12480
Step 21: 12480 + 624 = 13104
Step 22: 13104 + 624 = 13728
Step 23: 13728 + 624 = 14352
Step 24: 14352 + 624 = 14976
Step 25: 14976 + 624 = 15600
Step 26: 15600 + 624 = 16224
Step 27: 16224 + 624 = 16848
Step 28: 16848 + 624 = 17472
Step 29: 17472 + 624 = 18096
Step 30: 18096 + 624 = 18720
Step 31: 18720 + 624 = 19344
Step 32: 19344 + 624 = 19968
Step 33: 19968 + 624 = 20592
Step 34: 20592 + 624 = 21216
Step 35: 21216 + 624 = 21840
Step 36: 21840 + 624 = 22464
Step 37: 22464 + 624 = 23088
Step 38: 23088 + 624 = 23712

So, 624*38 = 23712
