12696126 ÷ 456 
We want to divide 12696126 by 456.

Let's proceed to step 1:
The number 456 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 456

Moving on to step 2:
If we divide 12 by 456, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 456

On to step 3:
456 goes into 126 0 times with a remainder of 126.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 126, we get 126.
Bring next digit (9) of the dividend behind the 126 and repeat the process: 1269 / 456

On to step 4:
1269 divided by 456 is 2 with a remainder of 357.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 912 from 1269 and we're left with 357.
Fetch the next digit (6) from the dividend, attach it to 357 and continue: 3576 / 456

On to step 5:
456 goes into 3576 7 times with a remainder of 384.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtracting 3192 from 3576 leaves us with 384.
Grab the next digit (1) from the dividend, add it to 384, then carry on: 3841 / 456

Going ahead to step 6:
If we divide 3841 by 456, we get 8 and a remainder of 193.
The number 8 becomes the next digit in our result. 
Result so far: 278.0
If we take 3648 away from 3841, we end up with 193.
Grab the next digit (2) from the dividend, add it to 193, then carry on: 1932 / 456

On to step 7:
1932 divided by 456 is 4 with a remainder of 108.
The number 4 becomes the next digit in our result. 
Result so far: 2784.0
If we subtract 1824 from 1932, we get 108.
Append the next digit (6) from the dividend to 108 and continue with: 1086 / 456

Advancing to step 8:
When dividing 1086 by 456, we get 2 with a remainder of 174.
Record the quotient 2 as the next digit in the result. 
Result so far: 27842.0
If we subtract 912 from 1086, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Going ahead to step 9:
1740 divided by 456 is 3 with a remainder of 372.
The number 3 becomes the next digit in our result. 
Result so far: 27842.3
If we subtract 1368 from 1740, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Going ahead to step 10:
3720 divided by 456 is 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 27842.38
If we subtract 3648 from 3720, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
456 can be fit into 720 1 times, resulting in a remainder of 264.
Write down 1 as next digit of the result. 
Result so far: 27842.381
The remainder is 264 after subtracting 456 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 12:
2640 divided by 456 is 5 with a remainder of 360.
The next digit of our result is 5. 
Result so far: 27842.3815
If we subtract 2280 from 2640, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 13:
3600 divided by 456 is 7 with a remainder of 408.
The number 7 becomes the next digit in our result. 
Result so far: 27842.38157
Subtract 3192 from 3600 to get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 14:
4080 divided by 456 is 8 with a remainder of 432.
Write down 8 as next digit of the result. 
Result so far: 27842.381578
Subtracting 3648 from 4080 leaves us with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Moving on to step 15:
456 goes into 4320 9 times with a remainder of 216.
The next digit of our result is 9. 
Result so far: 27842.3815789
If we subtract 4104 from 4320, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 16:
When dividing 2160 by 456, we get 4 with a remainder of 336.
Record the quotient 4 as the next digit in the result. 
Result so far: 27842.38157894
Deduct 1824 from 2160 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

In conclusion, the division gives 27842.38157894 with a balance of 3.36e-07.
