Subtract. Then write the difference in lowest terms. \[ \begin{array}{r} 56 \frac{7}{8} \\ -37 \frac{3}{8} \\ \hline \end{array} \]

Step 1 ：Subtract the whole numbers: \(56 - 37 = 19\)

Step 2 ：Subtract the fractions: \(\frac{7}{8} - \frac{3}{8} = \frac{1}{2}\)

Step 3 ：The result of the subtraction is \(19 \frac{1}{2}\)

Step 4 ：This is already in its simplest form, so no further simplification is needed.

Step 5 ：Final Answer: \(\boxed{19 \frac{1}{2}}\)
