teach me step by step how to learn division
Solution
Learning division step by step involves understanding the concept, the language used in division, and practicing different strategies. Here's a clear, step-by-step guide to help you learn division:
Step 1: Understanding Division
Division is the process of splitting a number (called the dividend) into equal parts. It's the opposite of multiplication.
- Example: If you have 12 cookies and you want to divide them equally among 3 people, each person gets 4 cookies. This is written as:
- Dividend: The number being divided (12).
- Divisor: The number you are dividing by (3).
- Quotient: The result (4).
Step 2: Relating Division to Multiplication
Since division is the opposite of multiplication, it's helpful to connect division problems with multiplication facts you already know. For example:
- because .
When dividing, think of what number you multiply by the divisor to get the dividend.
Step 3: Division Facts
Learn your multiplication tables (also called times tables), as division is based on them. If you know that:
- ,
- then .
Practice these division facts, starting with easier ones:
- 10 ÷ 2 = 5
- 15 ÷ 3 = 5
- 20 ÷ 4 = 5
Step 4: Long Division (For Larger Numbers)
For more complex problems, such as dividing larger numbers, you use long division. Here’s how to break down a long division problem like :
-
Step 1: Divide the first digit (7 divided by 4). 4 goes into 7 once. Write 1 above the 7.
-
Step 2: Multiply: Multiply 1 by 4 to get 4. Write that below 7.
-
Step 3: Subtract: Subtract 4 from 7 to get 3. Now, bring down the next digit (3).
-
Step 4: Divide the new number (33 divided by 4). 4 goes into 33 eight times. Write 8 above the 3.
-
Step 5: Multiply: Multiply 8 by 4 to get 32. Write that below 33.
-
Step 6: Subtract: Subtract 32 from 33 to get 1. Now, bring down the last digit (6).
-
Step 7: Divide the new number (16 divided by 4). 4 goes into 16 four times. Write 4 above the 6.
-
Step 8: Multiply and subtract: Multiply 4 by 4 to get 16. Subtract 16 from 16, which equals 0.
So, the final result is:
Step 5: Practice!
Once you’ve understood these concepts, practice with different problems, starting with simple ones and gradually working your way up to more complex division problems.

Further Questions for Practice:
- How do you divide numbers like 48 ÷ 6 using multiplication facts?
- Can you explain how long division works with two-digit divisors, such as 64 ÷ 8?
- How can we divide fractions, and how is it different from dividing whole numbers?
- What are some tips to improve accuracy with long division?
- What are some word problems that involve division and how would you solve them?
Tip: When dividing large numbers, break them into smaller, manageable parts. Divide step-by-step instead of trying to do everything at once!
