Let's get this math done. We have 804 and we're going to multiply it by 6. This is the same as taking 804 and adding it to itself 6 times.
Step 1: 0 + 804 = 804
Step 2: 804 + 804 = 1608
Step 3: 1608 + 804 = 2412
Step 4: 2412 + 804 = 3216
Step 5: 3216 + 804 = 4020
Step 6: 4020 + 804 = 4824

So, 804*6 = 4824
