Step 15: 8106 + 579 = 8685
Step 16: 8685 + 579 = 9264
Step 17: 9264 + 579 = 9843
Step 18: 9843 + 579 = 10422
Step 19: 10422 + 579 = 11001
Step 20: 11001 + 579 = 11580
Step 21: 11580 + 579 = 12159
Step 22: 12159 + 579 = 12738
Step 23: 12738 + 579 = 13317
Step 24: 13317 + 579 = 13896
Step 25: 13896 + 579 = 14475
Step 26: 14475 + 579 = 15054
Step 27: 15054 + 579 = 15633
Step 28: 15633 + 579 = 16212
Step 29: 16212 + 579 = 16791
Step 30: 16791 + 579 = 17370
Step 31: 17370 + 579 = 17949
Step 32: 17949 + 579 = 18528
Step 33: 18528 + 579 = 19107
Step 34: 19107 + 579 = 19686
Step 35: 19686 + 579 = 20265
Step 36: 20265 + 579 = 20844
Step 37: 20844 + 579 = 21423
Step 38: 21423 + 579 = 22002
Step 39: 22002 + 579 = 22581
Step 40: 22581 + 579 = 23160
Step 41: 23160 + 579 = 23739
Step 42: 23739 + 579 = 24318
Step 43: 24318 + 579 = 24897
Step 44: 24897 + 579 = 25476

So, 579*44 = 25476
