Every correct answer earns donations to The World Food Program. It's lots of fun and educational too! Long DivisionBelow is the process written out in full. You will often see other versions, which are generally just a shortened version of the process below. You can also see this done in Long Division Animation. Let's see how it is done with:  the number to be divided into is called the dividend
 The number which divides the other number is called the divisor
And here we go:
 4 ÷ 25 = 0 remainder 4  The first digit of the dividend (4) is divided by the divisor.    The whole number result is placed at the top. Any remainders are ignored at this point.  
 25 × 0 = 0  The answer from the first operation is multiplied by the divisor. The result is placed under the number divided into.   4 − 0 = 4  Now we subtract the bottom number from the top number.    Bring down the next digit of the dividend.   42 ÷ 25 = 1 remainder 17  Divide this number by the divisor.    The whole number result is placed at the top. Any remainders are ignored at this point.  
 25 × 1 = 25  The answer from the above operation is multiplied by the divisor. The result is placed under the last number divided into.   42 − 25 = 17  Now we subtract the bottom number from the top number.    Bring down the next digit of the dividend.   175 ÷ 25 = 7 remainder 0  Divide this number by the divisor.    The whole number result is placed at the top. Any remainders are ignored at this point.  
 25 × 7 = 175  The answer from the above operation is multiplied by the divisor. The result is placed under the number divided into.   175 − 175 = 0  Now we subtract the bottom number from the top number.    There are no more digits to bring down. The answer must be 17 
Method1 Calculating Double Digits by Double Digits1 Write the doubledigit numbers on top of each other. Place 1 of the doubledigit numbers on top and the other doubledigit number directly below it. While there's no right or wrong way to place the numbers, if you have a doubledigit that ends with a zero such as 40, place it on the bottom. This will let you skip a calculation. ^{[1]} For example, if you're multiplying 22 by 43, you can put either number on the top or bottom.
2 Multiply the bottom one's number by the top one's number. For the moment, don't worry about the bottom tens number. Just use the bottom one's number and multiply it by the one's number directly above it. Write the result directly below the line. ^{[2]} So for 22 x 43, you'll multiply 3 by 2 to get 6.
3 Multiply the bottom one's number by the number of the top ten. Use the same bottom number and multiply it by the number of the top ten. Then write the result under the line so it's directly below the tens space. ^{[3]} For example, with 22 x 43, you'll now need to multiply 3 by the other 2 to get 6. The number under your line should be 66.
4 Place a zero under your result. Before you begin multiplying the next part, place a zero under the one's place. This will hold the space so you can begin multiplying the bottom tens number. ^{[4]} So if you've got 66 as your first result, put a 0 right under the 6 in the ones place.
5 Multiply the bottom tens number by the top one's number. Now that you've already worked the bottom one's number, multiply the bottom tens number by the top one's number. Write the result next to the zero you wrote. ^{[5]} For example, 4 x 2 = 8, so write an 8 next to the 0.
6 Multiply the bottom tens number by the number of the top ten. Write the result next to the number you just wrote down.  For 4 x 2, write another 8 next to the 80 you already have written down.
7 Add both of your results to get a final answer. If your numbers don't have any more digits, you're ready to add both rows of your results. The number you get will be the answer. ^{[6]} For example, you'll need to add 66 + 880 to get 946
