We look at the division of 12814390 by 456 
We want to divide 12814390 by 456.

Advancing to step 1:
456 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 456

Step 2:
When dividing 12 by 456, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 456

On to step 3:
The number 456 fits into 128 0 times, leaving a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 128 after subtracting 0 from 128.
Include the next digit (1) from the dividend after 128, then repeat: 1281 / 456

Step 4:
456 goes into 1281 2 times with a remainder of 369.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 912 from 1281 to get 369.
Take the next digit (4) from the dividend and append it to 369, then repeat: 3694 / 456

Advancing to step 5:
456 goes into 3694 8 times with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we subtract 3648 from 3694, we get 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 456

Advancing to step 6:
463 divided by 456 is 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
If we take 456 away from 463, we end up with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 456

Going ahead to step 7:
When dividing 79 by 456, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 2810.0
Deduct 0 from 79 and we're left with 79.
Include the next digit (0) from the dividend after 79, then repeat: 790 / 456

Let's proceed to step 8:
790 divided by 456 is 1 with a remainder of 334.
Put 1 as the next digit of the answer. 
Result so far: 28101.0
Deduct 456 from 790 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Moving on to step 9:
If we divide 3340 by 456, we get 7 and a remainder of 148.
The next digit of our result is 7. 
Result so far: 28101.7
The remainder is 148 after subtracting 3192 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 10:
If we divide 1480 by 456, we get 3 and a remainder of 112.
The next digit of our result is 3. 
Result so far: 28101.73
Deduct 1368 from 1480 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Advancing to step 11:
If we divide 1120 by 456, we get 2 and a remainder of 208.
Record the quotient 2 as the next digit in the result. 
Result so far: 28101.732
The remainder is 208 after subtracting 912 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 12:
456 can be fit into 2080 4 times, resulting in a remainder of 256.
Use 4 as the next digit of our solution. 
Result so far: 28101.7324
The remainder is 256 after subtracting 1824 from 2080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 13:
When dividing 2560 by 456, we get 5 with a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 28101.73245
If we take 2280 away from 2560, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 14:
456 goes into 2800 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 28101.732456
Deduct 2736 from 2800 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
456 can be fit into 640 1 times, resulting in a remainder of 184.
Record the quotient 1 as the next digit in the result. 
Result so far: 28101.7324561
If we take 456 away from 640, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 16:
The number 456 fits into 1840 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 28101.73245614
If we subtract 1824 from 1840, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 28101.73245614 with a balance of 1.6e-08.
