We're dividing 12857947 by 426 
Our goal is to divide 12857947 by 426.

Let's proceed to step 1:
426 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 426

On to step 2:
When dividing 12 by 426, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 426

Let's proceed to step 3:
426 goes into 128 0 times with a remainder of 128.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Take the next digit (5) from the dividend and append it to 128, then repeat: 1285 / 426

Moving on to step 4:
426 goes into 1285 3 times with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1278 away from 1285, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 426

Let's proceed to step 5:
426 goes into 77 0 times with a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 77, we get 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 426

Let's proceed to step 6:
779 divided by 426 is 1 with a remainder of 353.
Put 1 as the next digit of the answer. 
Result so far: 301.0
The remainder is 353 after subtracting 426 from 779.
Take the next digit (4) from the dividend and append it to 353, then repeat: 3534 / 426

Let's proceed to step 7:
3534 divided by 426 is 8 with a remainder of 126.
The next digit of our result is 8. 
Result so far: 3018.0
Deduct 3408 from 3534 and we're left with 126.
Include the next digit (7) from the dividend after 126, then repeat: 1267 / 426

Going ahead to step 8:
426 goes into 1267 2 times with a remainder of 415.
The number 2 becomes the next digit in our result. 
Result so far: 30182.0
Deduct 852 from 1267 and we're left with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 9:
426 can be fit into 4150 9 times, resulting in a remainder of 316.
The next digit of our result is 9. 
Result so far: 30182.9
Subtract 3834 from 4150 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 10:
When dividing 3160 by 426, we get 7 with a remainder of 178.
Use 7 as the next digit of our solution. 
Result so far: 30182.97
Deduct 2982 from 3160 and we're left with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 11:
When dividing 1780 by 426, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 30182.974
Deduct 1704 from 1780 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 12:
The number 426 fits into 760 1 times, leaving a remainder of 334.
Use 1 as the next digit of our solution. 
Result so far: 30182.9741
Deduct 426 from 760 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.

Step 13:
426 goes into 3340 7 times with a remainder of 358.
The next digit of our result is 7. 
Result so far: 30182.97417
Subtracting 2982 from 3340 leaves us with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 14:
3580 divided by 426 is 8 with a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 30182.974178
If we take 3408 away from 3580, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Going ahead to step 15:
1720 divided by 426 is 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 30182.9741784
Subtracting 1704 from 1720 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 16:
The number 426 fits into 160 0 times, leaving a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 30182.9741784
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The quotient of the division is 30182.9741784, and the remainder is 1.6e-07.
