title: Split integer into equal chunks
body: <p>What is the most efficient and reliable way in Python to split sectors up like this:</p>
  
  <p>number: 101 (may vary of course)
  chunk1: 1 to 30 
  chunk2: 31 to 61
  chunk3: 62 to 92
  chunk4: 93 to 101</p>
  
  <p>Flow:
  copy sectors 1 to 30
  skip sectors in chunk 1 and copy 30 sectors starting from sector 31.
  and so on...</p>
  
  <p>I have this solved in a "manual" way using modules and basic math but there's got to be a function for this?</p>
  
  <p>Thank you.</p>
