Step 306: 200690 + 658 = 201348
Step 307: 201348 + 658 = 202006
Step 308: 202006 + 658 = 202664
Step 309: 202664 + 658 = 203322
Step 310: 203322 + 658 = 203980
Step 311: 203980 + 658 = 204638
Step 312: 204638 + 658 = 205296
Step 313: 205296 + 658 = 205954
Step 314: 205954 + 658 = 206612
Step 315: 206612 + 658 = 207270

So, 658*315 = 207270
