We look at the division of 12746219 by 634 
We're looking to find how many times 634 goes into 12746219.

Going ahead to step 1:
The number 634 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 634

Moving on to step 2:
If we divide 12 by 634, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 634

Going ahead to step 3:
If we divide 127 by 634, we get 0 and a remainder of 127.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 127, we get 127.
Bring next digit (4) of the dividend behind the 127 and repeat the process: 1274 / 634

Step 4:
The number 634 fits into 1274 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 1268 from 1274, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 634

On to step 5:
If we divide 66 by 634, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
The remainder is 66 after subtracting 0 from 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 634

Going ahead to step 6:
662 divided by 634 is 1 with a remainder of 28.
The next digit of our result is 1. 
Result so far: 201.0
The remainder is 28 after subtracting 634 from 662.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 634

Let's proceed to step 7:
The number 634 fits into 281 0 times, leaving a remainder of 281.
Record the quotient 0 as the next digit in the result. 
Result so far: 2010.0
Subtract 0 from 281 to get 281.
Bring next digit (9) of the dividend behind the 281 and repeat the process: 2819 / 634

On to step 8:
When dividing 2819 by 634, we get 4 with a remainder of 283.
The next digit of our result is 4. 
Result so far: 20104.0
The remainder is 283 after subtracting 2536 from 2819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 9:
If we divide 2830 by 634, we get 4 and a remainder of 294.
Write down 4 as next digit of the result. 
Result so far: 20104.4
Subtracting 2536 from 2830 leaves us with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 10:
634 can be fit into 2940 4 times, resulting in a remainder of 404.
Use 4 as the next digit of our solution. 
Result so far: 20104.44
Deduct 2536 from 2940 and we're left with 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

The final result is 20104.44 with a remainder of 0.404.
