Ignoring digits after the decimal point, if the number of digits in the numerator is at least two more than the number of digits in the denominator then the quotient is greater than 10.If the number of digits is only one more, then the first digit of the numerator must be greater than the first digit if the denominator. If they are the same, then the second digit of the N must be greater than the second digit of the D. If they are the same, compare the third digits and so on.Other wise, the quotient is not greater than 10.For example, you can multiply the divisor by 10 (just add a zero, if it's a whole number), and check whether the divident is greater than that, or not.
