Step 14: 4875 + 375 = 5250
Step 15: 5250 + 375 = 5625
Step 16: 5625 + 375 = 6000
Step 17: 6000 + 375 = 6375
Step 18: 6375 + 375 = 6750
Step 19: 6750 + 375 = 7125
Step 20: 7125 + 375 = 7500
Step 21: 7500 + 375 = 7875
Step 22: 7875 + 375 = 8250
Step 23: 8250 + 375 = 8625
Step 24: 8625 + 375 = 9000
Step 25: 9000 + 375 = 9375
Step 26: 9375 + 375 = 9750
Step 27: 9750 + 375 = 10125
Step 28: 10125 + 375 = 10500
Step 29: 10500 + 375 = 10875
Step 30: 10875 + 375 = 11250
Step 31: 11250 + 375 = 11625
Step 32: 11625 + 375 = 12000
Step 33: 12000 + 375 = 12375
Step 34: 12375 + 375 = 12750
Step 35: 12750 + 375 = 13125
Step 36: 13125 + 375 = 13500
Step 37: 13500 + 375 = 13875
Step 38: 13875 + 375 = 14250
Step 39: 14250 + 375 = 14625
Step 40: 14625 + 375 = 15000
Step 41: 15000 + 375 = 15375
Step 42: 15375 + 375 = 15750
Step 43: 15750 + 375 = 16125
Step 44: 16125 + 375 = 16500
Step 45: 16500 + 375 = 16875
Step 46: 16875 + 375 = 17250
Step 47: 17250 + 375 = 17625
Step 48: 17625 + 375 = 18000
Step 49: 18000 + 375 = 18375
Step 50: 18375 + 375 = 18750

So, 375*50 = 18750
