I'd love to help, but the question is kind of vague. What exactly do you have problems with? Have you read all the related posts about division in this blog? Have you checked out "The Pretty Good Guide to Prime Factorization" or "An Easy Way to do Long Division" at mathmojo.com? That last one should clear most stuff up for you. Leave a comment and let me know if it helped.

The bottom line of a division is typically a fraction, which conversely leads to division. The technique of “short division” is an interchange between division and fraction formats. Division is inverse to multiplication–we may multiply by zero but we cannot divide by zero. Short division is usually performed in reverse of multiplication. By far, when we refer to the division algorithm (use of multiplication and subtraction as support to division) both “short division” and “long division” use the border line formula of d=qxd+r. We can divide by “d” (divisor) in the formula where the fractional format compensates for the divisional context as one converging procedure.
D/d=q+r/d when d is not equal to zero. By and large, a short division means r=0 in the division formula where, typically, “d” can go “evenly” into “D” (dividend) as a result for “q” (the quotient of the division)–which interconnects multiplication and division as two inverse operations. When we “short” divide, we just turn any division into a fraction and we perform some canceling based on prime factorization as a shortcut to any division.

Notice:
Think about equivalent fractions, conversions of a fraction into decimal, percent or conversion of an improper fraction into a mixed number, repeating decimals, and so on and so forth.
