Understanding the Problem

When we divide a number by another number, we are essentially finding out how many times the divisor fits into the dividend. In this case, we need to divide 679 by 4. To do this, we will use the division algorithm, which involves finding the quotient (result of division) and the remainder (leftover amount).

The Division Algorithm

The division algorithm states that for any two integers a and b, with b > 0, there exist unique integers q and r such that:

a = bq + r

where q is the quotient and r is the remainder.

Applying the Division Algorithm to 679 and 4

To divide 679 by 4, we can use the division algorithm as follows:

679 = 4q + r

We need to find the value of q and r.

Step 1: Divide 679 by 4

To divide 679 by 4, we can start by multiplying 4 by the largest possible integer that is less than or equal to 679. This will give us the first part of the quotient.

4 × 169 = 676

Now, we subtract 676 from 679 to get the remainder.

679 - 676 = 3

Step 2: Find the Quotient and Remainder

From the previous step, we have:

q = 169 (since 4 × 169 = 676) r = 3 (since 679 - 676 = 3)

Therefore, the quotient is 169 and the remainder is 3.

Conclusion

In conclusion, when we divide 679 by 4, we get a quotient of 169 and a remainder of 3. This can be written as:

679 ÷ 4 = 169; R3

Answer

The correct answer is:

A. 169; R3

Why is this the Correct Answer?

This is the correct answer because we have followed the division algorithm to find the quotient and remainder. We have also checked our work by multiplying the quotient by the divisor and subtracting the product from the dividend. This ensures that our answer is accurate.
