Divide decimal currency evenly

Division where reminder is redistributed among results so that average delta is minimal.

Source

public static IEnumerable<decimal> DivideEvenly(this decimal total, int count, int round = 2)
{
	while (count > 0)
	{
		decimal value = Math.Round(total / count, round);
		total -= value;
		count--;
		yield return value;
	}
}

Example

var value = 26M;
var count = 6;
var round = 2;
var expected = new decimal[] { 4.33M, 4.33M, 4.34M, 4.33M, 4.34M, 4.33M };
var actual = value.DivideEvenly(count, round).ToArray();
Assert.Equal(expected, actual);
