Options

A. 4104
B. 40104
C. 41404
D. 41004

Answer

To solve the problem \( 641664 \div 16 \), we will follow these steps:

### Step 1: Set up the division
We need to divide \( 641664 \) by \( 16 \).

### Step 2: Perform the division
1. Start by seeing how many times \( 16 \) fits into the first part of \( 641664 \).
2. Since \( 16 \) does not fit into \( 6 \), we move to the next digit, making it \( 64 \).
3. \( 16 \) fits into \( 64 \) exactly \( 4 \) times because \( 16 \times 4 = 64 \).
4. Write \( 4 \) above the line.

### Step 3: Subtract and bring down the next digit
1. Subtract \( 64 \) from \( 64 \) to get \( 0 \).
2. Bring down the next digit, which is \( 1 \), making it \( 01 \).

### Step 4: Continue the division
1. \( 16 \) does not fit into \( 1 \), so we write \( 0 \) above the line.
2. Bring down the next digit, which is \( 6 \), making it \( 16 \).
3. \( 16 \) fits into \( 16 \) exactly \( 1 \) time. Write \( 1 \) above the line.

### Step 5: Subtract and bring down the next digit
1. Subtract \( 16 \) from \( 16 \) to get \( 0 \).
2. Bring down the next digit, which is \( 6 \), making it \( 06 \).

### Step 6: Finish the division
1. \( 16 \) does not fit into \( 6 \), so we write \( 0 \) above the line.
2. Bring down the last digit, which is \( 4 \), making it \( 64 \).
3. \( 16 \) fits into \( 64 \) exactly \( 4 \) times. Write \( 4 \) above the line.

### Step 7: Final subtraction
1. Subtract \( 64 \) from \( 64 \) to get \( 0 \).
2. Since there are no more digits to bring down, we conclude the division.

### Final Result
The result of \( 641664 \div 16 \) is \( 40104 \).
