1. Problem Description

The problem is to perform the division of 315 by

3. The expression is $315 \div 3$.

2. Solution Steps

To solve $315 \div 3$, we perform long division.

First, we divide 3 into

3. $3 \div 3 = 1$. Write 1 above the

3. Next, we multiply $1 \times 3 = 3$.

Subtract $3-3 = 0$.

Bring down the next digit,

1. Now we have

1. Divide 3 into

1. $1 \div 3 = 0$. Write 0 above the

1. Multiply $0 \times 3 = 0$.

Subtract $1 - 0 = 1$.

Bring down the next digit,

5. Now we have

1

5. Divide 3 into

1

5. $15 \div 3 = 5$. Write 5 above the

5. Multiply $5 \times 3 = 15$.

Subtract $15 - 15 = 0$.

Therefore, $315 \div 3 = 105$.

3. Final Answer

105
