20five / 14five

$$204_{\text{five}} = (2 \times 5^2) + (0 \times 5^1) + (4 \times 5^0)$$ $$= (2 \times 25) + (0 \times 5) + (4 \times 1)$$ $$= 50 + 0 + 4$$ $$= 54_{\text{ten}}$$

$$14_{\text{five}} = (1 \times 5^1) + (4 \times 5^0)$$ $$= (1 \times 5) + (4 \times 1)$$ $$= 5 + 4$$ $$= 9_{\text{ten}}$$

Tunagawanya 6 kwa 5 na kuandika mabaki:
$6 \div 5 = 1$ baki 1
$1 \div 5 = 0$ baki 1
Tukisoma mabaki kutoka chini kwenda juu, tunapata $11_{\text{five}}$.

Hivyo,

$$204_{\text{five}} \div 14_{\text{five}} = \boxed{11_{\text{five}}}$$
