This is because we count in tens so that the place value of a digit is ten times the place value of the digit to its right.

When you are multiplying a number by 10, you move the decimal point one place to the right. If you are multiplyingby 1,000, you move it 3 places to the right.You move the decimal point to the left when you are dividing by a multiple of 10.
It is not. For positive powers of ten, the decimal point moves to the right when multiplying and to the left when dividing. For negative powers of ten the point moves in the opposite directions.
Moving the decimal point one place to the right is the same as multiplying both, he numerator and the denominator by 10. That is, you are effectively multiplying by 10/10 which equals 1. And since multiplication by 1 does not change the result, it is OK to do that. Similarly, moving two palces to the right is multiplying by 100/100. Similarly moving left.

to the right to right to the right to the right not to the left to left to left lol have an awesome life
Multiplying a real number by a positive power of ten moves the decimal point that number (the exponent) of places to the right. Multiplying by a negative power of ten moves it to the left. For example, the -3 power of 10 is 1/1000; multiplying by that moves the decimal point 3 places to the left.
It you are multiplying by a number greater than one (or, equivalently, dividing by a number less than one) then the decimal would either stay put or move to the right.
Multiplying or dividing by ten.

0.10 = 1/10 so that multiplying by 0.10 is the same as dividing by 10.
Yes, by a number between 0 and 1.
When you move a decimal point to the right you are multiplying a number by 10. For example, take 3.4. If you move the decimal point to the right you get 34. This is the same as: 3.4x10 = 34. Reversing this, you are dividing by 10 by moving the decimal point to the left. For example, take 73. If you move the decimal point to the right you get 7.3. This is the same as: 73/10 = 7.3. If you move a decimal point 2 spaces to the right, you are multiplying by 100, or more generally if you move the decimal point n spaces to the right, you are multiplying by 10^n.
