To divide fractions, you can use the "keep, change, flip" rule:

1. Keep: Keep the first fraction the same

2. Change: Change the division sign to a multiplication sign

3. Flip: Flip the second fraction by switching its numerator and denominator

After flipping the second fraction, you can multiply the numerators together and then multiply the denominators together. If possible, you can simplify the answer or convert it to a mixed number. 

You can also understand dividing fractions by using number lines and jumps. For example, to divide 8/3 by 1/3, you can count how many jumps of 1/3 it takes to reach 8/3. 

Division of fractions involves using the reciprocal (flipped form) of the second fraction. The reciprocal of a number is such that the product of a number and its reciprocal is 1. To get the reciprocal, simply interchange (flip) the numerator and the denominator.
