Division is one of the 4 major operations in arithmetic, alongside addition, subtraction, and multiplication. In addition to whole numbers, you can divide decimals, fractions, or exponents. You can do long division or, if one of the numbers is a single digit, short division. Start by mastering long division, though, because it is the key to the ent...
Write out the problem using a
) looks like an ending parentheses attached to a horizontal line that goes over the string of numbers beneath the bar. Place the divisor, the number you'll be dividing into, outside the long division bar, and the dividend, the number that you'll be dividing, inside the long division bar.
Place the 5 outside the division bar, and the 65 inside it. It should look like
, but with the 65 underneath the horizontal line.
Place the 3 outside the division bar, and the 136 inside it. It should look like
, but with the 136 underneath the horizontal line.
Use a division bar to write out the problem.
Place the divisor, the number you'll be dividing into, outside of (and to the left of) the division bar. Put the dividend, the number that you'll be dividing, inside (to the right of and beneath) the division bar.
, your divisor can't have more than one digit.
In this case, the 4 will be outside the division bar, and the 518 inside it.
Divide your divisor into the first digit of the dividend.
In other words, determine how many times the number outside the division bar will fit into the first digit of the number inside the division bar. Write the whole number result above the division bar, and write any remainder (amount left over) in superscript beside the first digit of the dividend.
Write the equation so the 2 fractions are side-by-side.
, simply write the first fraction followed by the division symbol (÷) and the second fraction.
Your problem might be, for example,
For convenience, use horizontal instead of diagonal lines to separate the numerator (top number) and denominator (bottom number) of each fraction.
Reverse the numerator and denominator of the second fraction.
The second fraction becomes its own reciprocal.
Make sure the exponents have the same base.
if they have the same base. If they don't have the same base, you'll have to manipulate them until they do, if it's possible.
As a beginner, start with a sample problem in which both numbers with exponents already have the same base—for instance,
Simply subtract the second exponent from the first. Don't worry about the base for now.
8 - 5 = 3
Place the new exponent above the original base.
Write the problem out with a division bar.
Place the divisor, the number you'll be dividing into, outside (and to the left of) the long division bar, and the dividend, the number that you'll be dividing, inside the long division bar. To
, you’ll first convert the decimals into whole numbers.
, 0.5 goes outside the division bar, and 65.5 goes inside it.
Move the decimal points the same amount to create 2 whole numbers.
Just slide the decimal points to the right until they're at the end of each number. Make sure you move them the same amount for each number, though—if you have to move the decimal point 2 spots in the divisor, do the same for the dividend.
Division Practice Problems and Answers
How do I divide 9/10 to get to 3/6?
If you're asking what to divide into 9/10 in order to get 3/6, simply divide 3/6 into 9/10. Do that by inverting 3/6 and multiplying that by 9/10. Thus, (9/10) (6/3) = 54/30 = 9/5 = 1 4/5.

Division by 10: If we divide a number by 10, then the digit at the ones place will always be the remainder and the remaining digits on the left will be the quotient. For example, 579 ÷ 10 = 57 R 9. Division by 100: If we divide a number by 100, then the number formed from the ones place and the tens place digits will always be the remainder ...
