4.384615

Repeating decimal: denominator 13 has the factor 13, not 2 or 5 · the bar marks the period 384615 — 6 digits repeat forever

Whole part 4 stays in front; divide the fraction part:

remainder	×10	= digit × 13 + new remainder	digit
5	50	3 × 13 + 11	3
11	110	8 × 13 + 6	8
6	60	4 × 13 + 8	4
8	80	6 × 13 + 2	6
2	20	1 × 13 + 7	1
7	70	5 × 13 + 5	5

Remainder 5 is back after the 6th division → the 6 digits 384615 repeat: 0.384615.

4 + 0.384615 = 4.384615
