First step - We will make the decimal point in the dividend (the number we want to divide) disappear by moving it to the right the necessary number of places until it is completely "gone".
Second step - In the divisor (the second number in the operation, that is, the number by which it is divided) we will move the decimal point to the right the same number of places that we moved the first number (even if this number of steps is not enough to make it disappear)
Third step - We will solve the "new" exercise (with the "new" numbers).
