Step-by-step explanation:

                   8 6

           x    2 3 4

         --------------------

                 3 4 4

             2 5 8 0

           1 7 2 0 0

------------------------------

            2 0 1 2 4

0.86 has two numbers after the decimal point and 23.4 has one number after the decimal point

So we move 3 places to the left ( 20.124)

Mikayla moved the decimal incorrectly.
