Without delay, let's solve this. We've got 838 and we will be multiplying it by 10, that is, adding 838 to itself 10 times.
Step 1: 0 + 838 = 838
Step 2: 838 + 838 = 1676
Step 3: 1676 + 838 = 2514
Step 4: 2514 + 838 = 3352
Step 5: 3352 + 838 = 4190
Step 6: 4190 + 838 = 5028
Step 7: 5028 + 838 = 5866
Step 8: 5866 + 838 = 6704
Step 9: 6704 + 838 = 7542
Step 10: 7542 + 838 = 8380

So, 838*10 = 8380
