const str = readline()
const strlen = str.length
const strarr = []
if (strlen > 0) {
    const len = Math.ceil((strlen / 8))
    for (let i =0; i < len; i++) {
        strarr.push(str.slice(8 * i, 8 * (i+ 1)))
    }
}
const strarrlen = strarr.length
if (strarrlen > 0 && strarr[strarrlen - 1].length < 8) {
    const endStr = String(strarr[strarrlen - 1])
    strarr[strarrlen - 1] = endStr.padEnd(8, '0')
}
strarr.forEach(i => {
    console.log(i)
})

1. 不够8位补齐的方法用 str.padEnd(8, '0')
2. 切字符串使用方法 str.slice()
