Write the division problem using the longhand "divide by" symbol, which looks like a capital "L" rotated to the right. Put the dividend -- the number being divided into -- under the sign, and put the divisor -- the number used to divide -- to the left. For example, draw the symbol. Write 360 under it and 15 to the left of it. This means you're dividing 15 into 360.
Divide the divisor into the the first available numbers in the dividend. Write the result as a number on top of the symbol. For example, when you divide 15 into 360, 15 goes into 36 twice. Write the 2 above the 6.
Multiply the number in the quotient by the divisor and subtract the result from the dividend. Using the example, multiply 2 by 15 to get 30. Write 30 below 36 and subtract to get 6.
Divide your original divisor into this number if you can. If not, take the next number in the dividend and write it next to the number you just got when subtracting. In the example, 15 doesn't divide into 6, so you need another number. Write the 0 in 360 next to it to get 60. Now divide 15 into 60 for a result of 4. Write it above the 0 in the dividend. Your answer should be 14.
Repeat Step 3. For example, multiply the 4 by the 15 to get 60. Subtract this from the 60 to get 0. In other problems, you may have to keep dividing, multiplying and subtracting until you run out of numbers to bring down. If this happens and you get a number other than zero when subtracting, write that number as a remainder next to the quotient, or answer.
