What is 20/7 as a decimal?

Fraction 20/7 as a decimal is
2.857142

Repeating decimal: denominator 7 has the factor 7, not 2 or 5 · the bar marks the period 857142 — 6 digits repeat forever

20 ÷ 7 by long division

20 = 2 × 7 + 6: whole part 2, then divide the remainder 6

remainder×10= digit × 7 + new remainderdigit
6608 × 7 + 48
4405 × 7 + 55
5507 × 7 + 17
1101 × 7 + 31
3304 × 7 + 24
2202 × 7 + 62

Remainder 6 is back after the 6th division → the 6 digits 857142 repeat: 0.857142.

2 + 0.857142 = 2.857142
