To divide a larger number by a smaller number, you perform the division operation just as you would with any division problem.
Here's a breakdown of the process:
-
Set up the division problem: Write the larger number (the dividend) inside the division symbol and the smaller number (the divisor) outside the division symbol to the left.
______ Smaller | Larger
-
Perform the division: Determine how many times the divisor (smaller number) goes into the dividend (larger number). Start by looking at the first digit (or first few digits) of the dividend.
-
Write the quotient: Write the result (the quotient) above the division symbol, aligned with the digit(s) of the dividend you used.
-
Multiply: Multiply the divisor by the part of the quotient you just wrote.
-
Subtract: Subtract the result from the corresponding part of the dividend.
-
Bring down: Bring down the next digit of the dividend next to the result of the subtraction.
-
Repeat: Repeat steps 2-6 until you have no more digits to bring down in the dividend.
-
Remainder (if any): If there's a number left over after the last subtraction, that's the remainder. You can express the remainder as a fraction (remainder/divisor) or as a decimal by adding a decimal point and zeros to the dividend and continuing the division.
Example:
Let's divide 12 by 2.
-
Set up:
______ 2 | 12
-
Divide: How many times does 2 go into 1? It doesn't, so move to the next digit. How many times does 2 go into 12? It goes in 6 times.
-
Write the quotient:
6 2 | 12
-
Multiply: 2 * 6 = 12
-
Subtract: 12 - 12 = 0
6 2 | 12 -12 --- 0
Therefore, 12 divided by 2 is 6.
Example with Remainder and Decimal:
Let's divide 5 by 2.
-
Set up:
______ 2 | 5
-
Divide: How many times does 2 go into 5? It goes in 2 times.
-
Write the quotient:
2 2 | 5
-
Multiply: 2 * 2 = 4
-
Subtract: 5 - 4 = 1
2 2 | 5 -4 --- 1
-
Bring down: Since there are no more digits, we can add a decimal and a zero to continue to the decimal part of the answer.
2. 2 | 5.0 -4 --- 1 0
-
Divide: How many times does 2 go into 10? It goes in 5 times.
-
Write the quotient:
2.5 2 | 5.0 -4 --- 1 0 -1 0 ---- 0
Therefore, 5 divided by 2 is 2.5.
