### Core Algorithm or Logic

The core algorithm used by the Decimal to Octal Converter is based on dividing the decimal number by 8 repeatedly until the quotient is zero. At each step, the remainder is recorded and concatenated to form the octal number. The formula for the algorithm is as follows:

```
octal_num = ""
while decimal_num > 0:
remainder = decimal_num % 8
octal_num = str(remainder) + octal_num
decimal_num = decimal_num // 8
```

### Example Codes in Python, C, JavaScript, Java, and PHP

#### Python Code:

```
decimal_num = 1234567890
octal_num = ""
while decimal_num > 0:
remainder = decimal_num % 8
octal_num = str(remainder) + octal_num
decimal_num = decimal_num // 8
print(octal_num)
```

#### C Code:

```
#include <stdio.h>
int main() {
int decimal_num = 1234567890, octal_num = 0, i = 1;
while (decimal_num != 0) {
octal_num += (decimal_num % 8) * i;
decimal_num /= 8;
i *= 10;
}
printf("%d", octal_num);
return 0;
}
```

#### JavaScript Code:

```
const decimal_num = 1234567890;
let octal_num = "";
while (decimal_num > 0) {
let remainder = decimal_num % 8;
octal_num = remainder.toString() + octal_num;
decimal_num = Math.floor(decimal_num / 8);
}
console.log(octal_num);
```

#### Java Code:

```
public class DecimalToOctal {
public static void main(String[] args) {
int decimal_num = 1234567890;
StringBuilder octal_num = new StringBuilder();
while (decimal_num > 0) {
int remainder = decimal_num % 8;
octal_num.insert(0, remainder);
decimal_num /= 8;
}
System.out.println(octal_num);
}
}
```

#### PHP Code:

```
$decimal_num = 1234567890;
$octal_num = "";
while ($decimal_num > 0) {
$remainder = $decimal_num % 8;
$octal_num = strval($remainder) . $octal_num;
$decimal_num = intval($decimal_num / 8);
}
echo $octal_num;
```
