Step 310: 151101 + 489 = 151590
Step 311: 151590 + 489 = 152079
Step 312: 152079 + 489 = 152568
Step 313: 152568 + 489 = 153057
Step 314: 153057 + 489 = 153546
Step 315: 153546 + 489 = 154035
Step 316: 154035 + 489 = 154524
Step 317: 154524 + 489 = 155013
Step 318: 155013 + 489 = 155502

So, 489*318 = 155502
