Long Division Problem: Dividing 321 by 8 Step-by-Step

To solve the problem of dividing 321 by 8, we'll perform long division. Here are the steps:

• Step 1: Set up 321 as the dividend and 8 as the divisor.
• Step 2: Determine how many times 8 fits into the first digit of 321. Since 8 goes into 32 (the first two digits) four times without exceeding it, write 4 above the dividend.
• Step 3: Multiply 8 by 4 giving 32, and subtract 32 from 32, resulting in 0.
• Step 4: Bring down the next digit, 1, making the current number 1.
• Step 5: Determine how many times 8 fits into 1. It fits 0 times, placing a 0 in the quotient.
• Step 6: Since there are no more digits to bring down, 1 becomes the remainder.

Therefore, the quotient is 40 and the remainder is 1.

Thus, the solution to dividing 321 by 8 is: $\text{Quotient} = 40$, $\text{Remainder} = 1$.

According to the given choices, the correct choice is: $40$ with a remainder of 1
