can some one show me how to do long division?

OpenStudy (studygurl14):

Do you have a specific problem you need help with, or do you just want to learn long division in general?

OpenStudy (lcnettech):

no specific problem

Step 1: Division is even in all the digits We divide numbers where each of the hundreds, tens, and ones digits are evenly divisible by the divisor. The GOAL in this first, easy step is to get students used to two things: To get used to the long division "corner" so that the quotient is written on top. To get used to asking how many times does the divisor go into the various digits of the dividend. Step 2: A Remainder in the ones Now, there is a remainder in the ones (units). Thousands, hundreds, and tens digits still divide evenly by the divisor. First, students can solve the remainder mentally and simply write the remainder right after the quotient:Next, students learn to find the remainder using the process of "multiply & subtract". This is a very important step! The "multiply & subtract" part is often very confusing to students, so here we practice it in the easiest possible place: in the very end of the division, in the ones colum (instead of in the tens or hundreds column). Of course, this assumes that students have already learned to find the remainder in easy division problems that are based on the multiplication tables (such as 45 ÷ 7 or 18 ÷ 5). Step 3: A remainder in the tens In this step, students practice for the first time all the basic steps of long division algorithm: divide, multiply & subtract, drop down the next digit. We use two-digit numbers to keep it simple. Multiply & subtract has to do with finding the remainder, and after finding a remainder, we combine that with the next unit we are getting ready to divide (dropping down the digit). Step 4: A remainder in any of the place values After the previous step has been mastered, students then practice long division with three- and four-digit numbers where they will have to go through the basic steps several times.

hows that

OpenStudy (studygurl14):

Nice job @lsherron perhaps a drawing to demonstrate? some people are more visual, like me.

OpenStudy (anonymous):

ok ill put that to

OpenStudy (studygurl14):

:) you derserve lots of medals for that
