We look at the division of 12491026 by 628 
We want to divide 12491026 by 628.

Let's proceed to step 1:
When dividing 1 by 628, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 628

Going ahead to step 2:
628 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Fetch the next digit (4) from the dividend, attach it to 12 and continue: 124 / 628

Going ahead to step 3:
The number 628 fits into 124 0 times, leaving a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 124 leaves us with 124.
Append the next digit (9) from the dividend to 124 and continue with: 1249 / 628

Moving on to step 4:
628 can be fit into 1249 1 times, resulting in a remainder of 621.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 628 from 1249, we get 621.
Include the next digit (1) from the dividend after 621, then repeat: 6211 / 628

Advancing to step 5:
If we divide 6211 by 628, we get 9 and a remainder of 559.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 5652 from 6211 and we're left with 559.
Bring next digit (0) of the dividend behind the 559 and repeat the process: 5590 / 628

Going ahead to step 6:
If we divide 5590 by 628, we get 8 and a remainder of 566.
The number 8 becomes the next digit in our result. 
Result so far: 198.0
The remainder is 566 after subtracting 5024 from 5590.
Take the next digit (2) from the dividend and append it to 566, then repeat: 5662 / 628

On to step 7:
628 goes into 5662 9 times with a remainder of 10.
The number 9 becomes the next digit in our result. 
Result so far: 1989.0
Deduct 5652 from 5662 and we're left with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 628

Let's proceed to step 8:
The number 628 fits into 106 0 times, leaving a remainder of 106.
The next digit of our result is 0. 
Result so far: 19890.0
If we subtract 0 from 106, we get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 9:
628 goes into 1060 1 times with a remainder of 432.
Write down 1 as next digit of the result. 
Result so far: 19890.1
If we take 628 away from 1060, we end up 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.

Step 10:
If we divide 4320 by 628, we get 6 and a remainder of 552.
Record the quotient 6 as the next digit in the result. 
Result so far: 19890.16
Deduct 3768 from 4320 and we're left with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

Going ahead to step 11:
628 can be fit into 5520 8 times, resulting in a remainder of 496.
The next digit of our result is 8. 
Result so far: 19890.168
Subtract 5024 from 5520 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Going ahead to step 12:
When dividing 4960 by 628, we get 7 with a remainder of 564.
Record the quotient 7 as the next digit in the result. 
Result so far: 19890.1687
The remainder is 564 after subtracting 4396 from 4960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Advancing to step 13:
628 can be fit into 5640 8 times, resulting in a remainder of 616.
The number 8 becomes the next digit in our result. 
Result so far: 19890.16878
If we subtract 5024 from 5640, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Advancing to step 14:
628 can be fit into 6160 9 times, resulting in a remainder of 508.
The number 9 becomes the next digit in our result. 
Result so far: 19890.168789
Subtracting 5652 from 6160 leaves us with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 15:
628 can be fit into 5080 8 times, resulting in a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 19890.1687898
Subtract 5024 from 5080 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 16:
628 can be fit into 560 0 times, resulting in a remainder of 560.
The number 0 becomes the next digit in our result. 
Result so far: 19890.1687898
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final result is 19890.1687898 with a remainder of 5.6e-07.
