Step 320: 100804 + 316 = 101120
Step 321: 101120 + 316 = 101436
Step 322: 101436 + 316 = 101752
Step 323: 101752 + 316 = 102068
Step 324: 102068 + 316 = 102384
Step 325: 102384 + 316 = 102700
Step 326: 102700 + 316 = 103016
Step 327: 103016 + 316 = 103332
Step 328: 103332 + 316 = 103648

So, 316*328 = 103648
