We're dividing 12430950 by 455 
We want to divide 12430950 by 455.

On to step 1:
455 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 455

Let's proceed to step 2:
When dividing 12 by 455, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 455

Moving on to step 3:
When dividing 124 by 455, we get 0 with a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 124 after subtracting 0 from 124.
Grab the next digit (3) from the dividend, add it to 124, then carry on: 1243 / 455

Advancing to step 4:
455 goes into 1243 2 times with a remainder of 333.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 333 after subtracting 910 from 1243.
Grab the next digit (0) from the dividend, add it to 333, then carry on: 3330 / 455

Step 5:
455 can be fit into 3330 7 times, resulting in a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 3185 from 3330 leaves us with 145.
Include the next digit (9) from the dividend after 145, then repeat: 1459 / 455

Let's proceed to step 6:
455 goes into 1459 3 times with a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 273.0
If we subtract 1365 from 1459, we get 94.
Append the next digit (5) from the dividend to 94 and continue with: 945 / 455

Going ahead to step 7:
945 divided by 455 is 2 with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 2732.0
If we take 910 away from 945, we end up with 35.
Bring next digit (0) of the dividend behind the 35 and repeat the process: 350 / 455

Step 8:
When dividing 350 by 455, we get 0 with a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 27320.0
If we take 0 away from 350, we end up with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Advancing to step 9:
3500 divided by 455 is 7 with a remainder of 315.
Use 7 as the next digit of our solution. 
Result so far: 27320.7
Deduct 3185 from 3500 and we're left with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Moving on to step 10:
455 goes into 3150 6 times with a remainder of 420.
Put 6 as the next digit of the answer. 
Result so far: 27320.76
If we subtract 2730 from 3150, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
455 goes into 4200 9 times with a remainder of 105.
The number 9 becomes the next digit in our result. 
Result so far: 27320.769
Deduct 4095 from 4200 and we're left with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 12:
1050 divided by 455 is 2 with a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 27320.7692
If we take 910 away from 1050, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 13:
455 goes into 1400 3 times with a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 27320.76923
Subtract 1365 from 1400 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
455 can be fit into 350 0 times, resulting in a remainder of 350.
The next digit of our result is 0. 
Result so far: 27320.76923
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Going ahead to step 15:
3500 divided by 455 is 7 with a remainder of 315.
Write down 7 as next digit of the result. 
Result so far: 27320.7692307
Subtract 3185 from 3500 to get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 16:
3150 divided by 455 is 6 with a remainder of 420.
Record the quotient 6 as the next digit in the result. 
Result so far: 27320.76923076
If we subtract 2730 from 3150, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

In conclusion, the division gives 27320.76923076 with a balance of 4.2e-07.
