The sum of 123 by 0.2321 is 529.5881 (rounded to four decimal places).

Here is the detailed calculation:

Step 1: Write the long division problem with the dividend (123) inside the division symbol and the divisor (0.2321) outside the division symbol:

```
     529.5881
  --------------
 0.2321 | 123.0000

```

Step 2: Divide the first digit of the dividend by the divisor. In this case, 1 divided by 0.2321 is 4.3098 (rounded to four decimal places). Write this result above the dividend, aligned with the first digit:

```
      4.3098
     ---------
 0.2321 | 123.0000
```

Step 3: Multiply the divisor by the quotient obtained in Step 2, and write the result below the first digit of the dividend, aligned with the second digit:

```

      4.3098
     ---------
 0.2321 | 123.0000
           0.9284
```

Step 4: Subtract the result from Step 3 from the first two digits of the dividend. Write the result below the line:

```

      4.3098
     ---------
 0.2321 | 123.0000
           0.9284
     ---------
         30.0716
```

Step 5: Bring down the next digit of the dividend (in this case, 0) and write it next to the result from Step 4:

```

      4.3098
     ---------
 0.2321 | 123.0000
           0.9284
     ---------
         30.0716
          0
```

Step 6: Divide the result from Step 5 by the divisor, and write the quotient above the next digit of the dividend:

```

      4.3098
     ---------
 0.2321 | 123.0000
           0.9284
     ---------
         30.0716
          0.5151
```

Step 7: Multiply the divisor by the quotient obtained in Step 6, and write the result below the next digit of the dividend:

```

      4.3098
     ---------
 0.2321 | 123.0000
           0.9284
     ---------
         30.0716
          0.5151
     ---------
          1.0733
```

Step 8: Subtract the result from Step 7 from the next two digits of the dividend. Write the result below the line:

```

      4.3098
     ---------
 0.2321 | 123.0000
           0.9284
     ---------
         30.0716
          0.5151
     ---------
          1.0733
          1.1600
```

Step 9: Repeat Steps 5 to 8 until all digits of the dividend have been brought down:

```

      4.3098
     ---------
 0.2321 | 123.0000
           0.9284
     ---------
         30.0716
          0.5151
     ---------
          1.0733
          1.1600
          0
```

Step 10: Round the quotient to the desired number of decimal places. In this case, rounding to four decimal places gives us 529.5881 as the final answer.

So, the calculation of the sum of 123 by 0.2321 involves dividing 123 by 0.2321 using long division, as described above. The result is 529.5881, which can be rounded to four decimal places if desired.
