To convert an integer to base triangle:

Write the integer as a group of ones (6 is shown below).

1 1 1 1 1 1

Iteratively redistribute the leftmost value, adding 1 to each value to its right.

2 1 1 1 1

2 2 1 1

3 2 1

Stop when the leftmost value is greater than the number of values to its right.
