- 1. Introduction to Long Division • Definition: Long division is a method used to divide large numbers by breaking down the division into simpler steps. • Purpose: It helps solve division problems when the divisor has multiple digits. • Example: Dividing 256 by 4.
- 2. Steps of Long Division • 1. Divide: How many times does the divisor fit into the first digit(s) of the dividend? • 2. Multiply: Multiply the divisor by the quotient from Step 1. • 3. Subtract: Subtract the result from the number you divided. • 4. Bring Down: Bring down the next digit of the dividend. • Repeat these steps until all digits are brought down.
- 3. Example Problem: 432 ÷ 3 • 1. Divide: 3 goes into 4 one time. • 2. Multiply: 1 × 3 = 3. • 3. Subtract: 4 - 3 = 1. • 4. Bring Down: Bring down the 3 to make 13. • Repeat until you get the answer. • Answer: 432 ÷ 3 = 144
- 4. Practice Problems • Try solving these: • - 128 ÷ 4 • - 256 ÷ 8 • - 396 ÷ 6 • Check your answers by multiplying the quotient by the divisor.
