Sure thing, let's get straight to it. We start with 877 and we're going to multiply it by 6, which means adding 877 to itself 6 times.
Step 1: 0 + 877 = 877
Step 2: 877 + 877 = 1754
Step 3: 1754 + 877 = 2631
Step 4: 2631 + 877 = 3508
Step 5: 3508 + 877 = 4385
Step 6: 4385 + 877 = 5262

So, 877*6 = 5262
