Brincando com go... But, tem será maneira mais 'go-style' de fazer isso?

divisible.go

package main

import "os"
import "fmt"
import "math"
import "strconv"

func main() {
    number, _ := strconv.ParseFloat(os.Args[1:2][0], 64)
    denom := float64(2)
    _number := float64(0)

    for number > 0 {
        denom = math.Ceil(1/number)
        _number = number - (1/denom)
        fmt.Println("1 /", denom, "\n=", _number)
        number = _number
    }
}

Talvez assim.. :)

package main

import "os"
import "fmt"
import "math"
import "strconv"

func main() {
    if len(os.Args) != 2 {
        panic("Usage: ./file float")
    }

    number, err := strconv.ParseFloat(os.Args[1:2][0], 64)

    if err != nil {
        panic(err)
    }

    denom := float64(2)

    for number > 0 {
        denom = math.Ceil(1/number)
        fmt.Println("1 /", denom)

        number -= (1/denom)
        fmt.Println("=", number)
    }
}
