Calculate Area with Perpendicular Lines: 15 and 1140 Units Problem

To solve this division problem of dividing 1140 by 15, we perform the following steps:

• Step 1: Set up the division with 1140 under the division bracket and 15 outside.
• Step 2: Determine how many times 15 fits into the first two digits of the dividend, 11. Since it doesn't fit, consider the first three digits, 114.
• Step 3: Calculate $15 \times 7 = 105$, which is the nearest lower product to 114. Write 7 above the division bar.
• Step 4: Subtract 105 from 114, leaving 9. Bring down the next digit of the dividend, 0, making it 90.
• Step 5: Determine how many times 15 fits into 90. $15 \times 6 = 90$. Write 6 above the division bar.
• Step 6: Subtract the 90 from 90, resulting in a remainder of 0.

The quotient from the division of 1140 by 15 is $76$. None remains, confirming complete division.

Therefore, the solution to the problem is $76$.
