OK, let's crack this. We're given 191 and our task is to multiply it by 10. Essentially, we'll be adding 191 to itself 10 times.
Step 1: 0 + 191 = 191
Step 2: 191 + 191 = 382
Step 3: 382 + 191 = 573
Step 4: 573 + 191 = 764
Step 5: 764 + 191 = 955
Step 6: 955 + 191 = 1146
Step 7: 1146 + 191 = 1337
Step 8: 1337 + 191 = 1528
Step 9: 1528 + 191 = 1719
Step 10: 1719 + 191 = 1910

So, 191*10 = 1910
