Question

use the partial quotients method to find 813 ÷ 30. fill in the missing numbers.

Explanation:

Step1: First partial - quotient

We know that $30\times10 = 300$. Since $813-300 = 513$, the first number we subtract $300$ comes from $10\times30$.

Step2: Second partial - quotient

Again, subtracting $300$ from $513$ (i.e., $513 - 300=213$), and $300$ is $10\times30$.

Step3: Third partial - quotient

We subtract $210$ from $213$ and $210 = 7\times30$. And $213-210 = 3$.
The sum of the partial - quotients is $10 + 10+7=27$.

Answer:

$27$ R $3$
