"Direct division" refers to the method of quickly getting the first place (first place or top two) of quotient through "direct division" when comparing or calculating complicated fractions, so as to get the correct answer.

Before the application of direct division, it is generally estimated first, and at the same time, direct division can solve most of the division calculation problems in the test paper.

Method one

If the first digit of the divisor is 1 or 2, directly divide by the first three digits of the divisor;

If the difference between the options is particularly small, divide it directly by the divisor.

Method 2

If the first two or three digits of the options are different, the answer is judged by dividing by the first two digits of the divisor, that is, the first two digits of the divisor are taken as the calculation result.

Method 3

If the first choice is different, judge the answer by judging the first result. The specific method is to judge the first result by "trial quotient".
