Explain how to solve the following problem in paragraph form. 7 5/6 - (-4 1/7)

Convert to a mixed number:
503/42
Divide 503 by 42:
4 | 2 | 5 | 0 | 3
42 goes into 50 at most one time:
 | | | 1 | | 
4 | 2 | 5 | 0 | 3 | 
 | - | 4 | 2 | | 
 | | | 8 | 3 |  
42 goes into 83 at most one time:
 | | | 1 | 1 | 
4 | 2 | 5 | 0 | 3 | 
 | - | 4 | 2 | | 
 | | | 8 | 3 | 
 | | - | 4 | 2 | 
 | | | 4 | 1 | 
The quotient of 503/42 is 11 with remainder 41, so:
  11 41/42
