Solve Division Problem: 4.2 ÷ 0.001 Step-by-Step

To solve this problem, we'll follow these steps:

• Step 1: Adjust the decimal places to simplify the division.
• Step 2: Scale the numbers to eliminate the decimal point in the divisor.
• Step 3: Perform the division with whole numbers.

Now, let's work through each step:
Step 1: We need to divide $4.2$ by $0.001$.
Step 2: Multiply both the dividend $4.2$ and the divisor $0.001$ by $1000$ to avoid decimal division. This gives us:

• $4.2 \times 1000 = 4200$
• $0.001 \times 1000 = 1$

Step 3: Now, divide $4200$ by $1$:

$4200 \div 1 = 4200$

Therefore, the solution to the problem is $4200$.
