The place value of each digit is one tenth of the place value of the digit to its right. So moving the decimal point to the left is the same as changing the place value of each digit to a tenth - which is what division by 10 entails. For integral powers of 10 it is simply a repetition of this process.

Why can you move the decimal point when dividing?
If you move the decimal point the same direction and number of places for the dividend and the divisor, this accomplishes the same thing as multiplying (or dividing) a numerator and denominator by the same number (in this case it is a power of ten). Moving the decimal place to the right by one place effectively multiplies the number by 10, and moving the decimal place to the left by one place is the same as dividing the number by 10. Example: 12345.6 / 10 = 1234.56
