It sounds like you want to convert 221 from base 10 to base 5.
The largest power of 5 that fits into 221 is 5³ = 125, and
221 = 125 + 96
221 = 1•5³ + 96
The largest power of 5 that fits into the remainder 96 is 5² = 25, and
96 = 75 + 21
96 = 3•25 + 21
96 = 3•5² + 21
→ 221 = 1•5³ + 3•5² + 21
The largest power of 5 that fits into the remainder 21 is 5¹ = 5, and
21 = 20 + 1
21 = 4•5¹ + 1
→ 221 = 1•5³ + 3•5² + 4•5¹ + 1
Finally, 1 = 5⁰, so
221 = 1•5³ + 3•5² + 4•5¹ + 1•5⁰
and
221₁₀ = 1341₅
