Without delay, let's solve this. We've got 519 and we will be multiplying it by 10, that is, adding 519 to itself 10 times.
Step 1: 0 + 519 = 519
Step 2: 519 + 519 = 1038
Step 3: 1038 + 519 = 1557
Step 4: 1557 + 519 = 2076
Step 5: 2076 + 519 = 2595
Step 6: 2595 + 519 = 3114
Step 7: 3114 + 519 = 3633
Step 8: 3633 + 519 = 4152
Step 9: 4152 + 519 = 4671
Step 10: 4671 + 519 = 5190

So, 519*10 = 5190
