To divide the mixed number \(4 \frac{2}{1}\) by the mixed number \(7 \frac{5}{1}\), we first convert the mixed numbers into improper fractions.

  1. Convert \(4 \frac{2}{1}\): \[ 4 \frac{2}{1} = 4 + \frac{2}{1} = \frac{4 \times 1 + 2}{1} = \frac{4 + 2}{1} = \frac{6}{1} \]

  2. Convert \(7 \frac{5}{1}\): \[ 7 \frac{5}{1} = 7 + \frac{5}{1} = \frac{7 \times 1 + 5}{1} = \frac{7 + 5}{1} = \frac{12}{1} \]

Now, we have the problem:

\[ \frac{6}{1} \div \frac{12}{1} \]

Dividing by a fraction is the same as multiplying by its reciprocal:

\[ \frac{6}{1} \div \frac{12}{1} = \frac{6}{1} \times \frac{1}{12} = \frac{6 \times 1}{1 \times 12} = \frac{6}{12} \]

Now simplify \(\frac{6}{12}\):

\[ \frac{6}{12} = \frac{1}{2} \]

Thus, the answer is:

\[ \frac{1}{2} \] or as a mixed number, it remains \(\frac{1}{2}\).
