1) To divide a decimal by 10 or a power of 10, shift the decimal point to the left by as many places as there are zeros in the divisor (that is, 10 or a power of 10).
For e.g.: 34.5/10 = 3.45.
We know that the number of zeros in 10 is 1 so, on dividing by 10, the decimal point is shifted to the left by one place
