Answer Key for Three-Digit Division Math Worksheet

You’ve uploaded an answer key for a math worksheet titled:

> “Easy Division with Remainders Three-Digit Math Worksheet 4”

This is not a problem to solve — it’s the solution sheet showing the correct answers for each division problem.

---

🧾 What’s on the Sheet?

It contains 12 long division problems, each dividing a three-digit number by a one-digit number, and includes the quotient and remainder (e.g., `128 r1`, meaning 128 with a remainder of 1).

Each problem is laid out vertically in the standard long division format, with the dividend inside the bracket and the divisor outside. The quotient is written above, and the subtraction steps are shown below.

✔ Example Breakdown:

Let’s take the first problem:

```
128 r1
_______
4 | 513
4
--
11
8
--
33
32
--
1 ← remainder
```

✔ Check:
`4 × 128 = 512`, and `512 + 1 = 513` → Correct!

🔢 All Problems Solved (as per answer key):

| Problem | Quotient & Remainder |
|-----------------|----------------------|
| 513 ÷ 4 | 128 r1 |
| 489 ÷ 2 | 222 r3 |
| 327 ÷ 4 | 73 r2 |
| 952 ÷ 2 | 476 |
| 579 ÷ 4 | 145 r4 |
| 858 ÷ 3 | 286 |
| 604 ÷ 4 | 166 |
| 432 ÷ 2 | 216 |
| 547 ÷ 4 | 132 r1 |

*(Note: The last three problems are partially cut off in your image, but from context and layout, they’re likely:)*

Assuming continuation:

| Problem | Quotient & Remainder |
|-----------------|----------------------|
| 489 ÷ 2 | 222 r3 |
| 327 ÷ 4 | 73 r2 |
| 858 ÷ 3 | 286 |

Wait — actually, looking at the layout again, there are 12 problems total, arranged in 3 rows of 4 columns. The full set is visible.

📊 Summary Table (All 12 Problems):

| Dividend | Divisor | Quotient | Remainder |
|----------|---------|----------|---------|
| 513 | 4 | 128 | 1 |
| 489 | 2 | 222 | 3 |
| 327 | 4 | 73 | 2 |
| 952 | 2 | 476 | 0 |
| 579 | 4 | 145 | 4 |
| 858 | 3 | 286 | 0 |
| 604 | 4 | 166 | 0? *(Actually 604 ÷ 4 = 151, so this might be a typo — see note below)* |
| 432 | 2 | 216 | 0 |
| 547 | 4 | 132 | 1? *(Actually 547 ÷ 4 = 136 r3 — another possible typo)* |
| *(Row 3, col 1)* | ? | ? | ? — *Partially cut off* |

⚠️ Important Note: There appear to be errors in the answer key for some problems:

#### ✘ Problem 3: 604 ÷ 4
- Answer key says: 166
- Actual: `4 × 166 = 664` → Too big!
- Correct: `604 ÷ 4 = 151` (exactly, no remainder)

#### ✘ Problem 9: 547 ÷ 4
- Answer key says: 132 r1
- Check: `4 × 132 = 528`; `547 - 528 = 19` → Not 1.
- Correct: `4 × 136 = 544`; `547 - 544 = 3` → So 136 r3

So — while this is labeled “Answer Key”, it contains at least two calculation errors.

✍️ Final Thoughts:

- This is not a problem to solve — it’s already solved (though incorrectly in places).
- If you were given this as a student worksheet, you’d fill in the blanks using these answers.
- If you’re a teacher or parent checking work, be aware of the errors in problems 3 and 9.
- You can use this to practice long division by redoing the problems yourself and comparing results.

💡 Tip for Learning:

When doing long division:
1. Divide → Multiply → Subtract → Bring down → Repeat.
2. Always check: `(Divisor × Quotient) + Remainder = Dividend`

Example: For `513 ÷ 4 = 128 r1` → `(4 × 128) + 1 = 512 + 1 = 513` ✔️

✔ Conclusion: The sheet is an answer key with minor errors. Use it for practice, but verify the math yourself — especially problems #3 and #9.
