Step 322: 47508 + 148 = 47656
Step 323: 47656 + 148 = 47804
Step 324: 47804 + 148 = 47952
Step 325: 47952 + 148 = 48100
Step 326: 48100 + 148 = 48248
Step 327: 48248 + 148 = 48396
Step 328: 48396 + 148 = 48544
Step 329: 48544 + 148 = 48692
Step 330: 48692 + 148 = 48840
Step 331: 48840 + 148 = 48988

So, 148*331 = 48988
