title: How to divide a number into multiple parts so that the resulting sum is equal to the input?
body: <p>I am trying to divide a number into multiple parts so the sum of the part are equal to the input number.</p>
  
  <p>If I have 3.99 and if I need to divide into two parts, the expected output is 2 and 1.99 (2+1.99=3.99)</p>
  
  <p>And if I need to divide 3.99 into 3 parts, the expected output is 1.3, 1.3 and 1.39 (1.3+1.3+1.39=3.99)</p>
  
  <p>I was able to output 2.99 and 1 for the first example and I was able to get 1.99, 1 and 1 for the second example. However, in both the cases results are very far from the expected output.</p>
  
  <p>I need to split postal charges into separate line items. The result could be equally divided or unequally divided while making sure that the sum of the different parts is equal to the input number.</p>
  
  <p>Here are some other examples:</p>
  
  <pre><code>3.99 divided in 3 parts: 1.33, 1.33, 1.33
  3.98 divided in 3 parts: 1.33, 1.33, 1.32
  3.97 divided in 3 parts: 1.32, 1.32, 1.33
  3.96 divided in 3 parts: 1.32, 1.32, 1.32
  3.95 divided in 3 parts: 1.32, 1.32, 1.31
