• 779 ÷ 5 = 155.8 — not a whole number
• 779 ÷ 6 = 129.833 — not a whole number
• 779 ÷ 7 = 111.286 — not a whole number
• 779 ÷ 8 = 97.375 — not a whole number
• 779 ÷ 9 = 86.556 — not a whole number
• 779 ÷ 10 = 77.9 — not a whole number
• 779 ÷ 11 = 70.818 — not a whole number
• 779 ÷ 12 = 64.917 — not a whole number
• 779 ÷ 13 = 59.923 — not a whole number
• 779 ÷ 14 = 55.643 — not a whole number
• 779 ÷ 15 = 51.933 — not a whole number
