$$ 19 \div \square = 6 \cdots 1 $$

Question

UpStudy AI · Accepted Answer

We are given the division with a missing divisor:

$$
19 \div \square = 6 \cdots 1
$$

This means that when $$ 19 $$ is divided by the unknown number (denote it by $$ d $$), the quotient is $$ 6 $$ and the remainder is $$ 1 $$. According to the division algorithm, we have:

$$
19 = d \times 6 + 1
$$

**Step 1:** Subtract the remainder from the dividend:

$$
19 - 1 = 18
$$

**Step 2:** Set up the equation to solve for $$ d $$:

$$
d \times 6 = 18
$$

**Step 3:** Divide both sides by $$ 6 $$ to find $$ d $$:

$$
d = \frac{18}{6}
$$

$$
d = 3
$$

Thus, the missing number is $$ 3 $$.
The missing number is 3.

\( 19 \div \square = 6 \cdots 1 \)
