The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 459

Advancing to step 2:
If we divide 12 by 459, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 459

On to step 3:
459 goes into 128 0 times with a remainder of 128.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 128 after subtracting 0 from 128.
Fetch the next digit (5) from the dividend, attach it to 128 and continue: 1285 / 459

Let's proceed to step 4:
459 goes into 1285 2 times with a remainder of 367.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 918 from 1285 and we're left with 367.
Take the next digit (8) from the dividend and append it to 367, then repeat: 3678 / 459

On to step 5:
459 can be fit into 3678 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we subtract 3672 from 3678, we get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 459

Going ahead to step 6:
459 goes into 68 0 times with a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 280.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 459

Moving on to step 7:
When dividing 685 by 459, we get 1 with a remainder of 226.
Put 1 as the next digit of the answer. 
Result so far: 2801.0
Subtract 459 from 685 to get 226.
Append the next digit (4) from the dividend to 226 and continue with: 2264 / 459

On to step 8:
459 goes into 2264 4 times with a remainder of 428.
The number 4 becomes the next digit in our result. 
Result so far: 28014.0
If we take 1836 away from 2264, we end up with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Step 9:
When dividing 4280 by 459, we get 9 with a remainder of 149.
The next digit of our result is 9. 
Result so far: 28014.9
Deduct 4131 from 4280 and we're left with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

On to step 10:
459 goes into 1490 3 times with a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 28014.93
Subtract 1377 from 1490 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

On to step 11:
459 goes into 1130 2 times with a remainder of 212.
Write down 2 as next digit of the result. 
Result so far: 28014.932
If we subtract 918 from 1130, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 12:
When dividing 2120 by 459, we get 4 with a remainder of 284.
The next digit of our result is 4. 
Result so far: 28014.9324
If we take 1836 away from 2120, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 13:
If we divide 2840 by 459, we get 6 and a remainder of 86.
The number 6 becomes the next digit in our result. 
Result so far: 28014.93246
If we subtract 2754 from 2840, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 14:
860 divided by 459 is 1 with a remainder of 401.
Put 1 as the next digit of the answer. 
Result so far: 28014.932461
If we take 459 away from 860, we end up with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Going ahead to step 15:
The number 459 fits into 4010 8 times, leaving a remainder of 338.
Write down 8 as next digit of the result. 
Result so far: 28014.9324618
If we take 3672 away from 4010, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 16:
The number 459 fits into 3380 7 times, leaving a remainder of 167.
The number 7 becomes the next digit in our result. 
Result so far: 28014.93246187
The remainder is 167 after subtracting 3213 from 3380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

In conclusion, the division gives 28014.93246187 with a balance of 1.67e-07.
