We look at the division of 12860294 by 674 
We want to divide 12860294 by 674.

Let's proceed to step 1:
674 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the 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 / 674

Let's proceed to step 2:
674 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 674

Let's proceed to step 3:
If we divide 128 by 674, we get 0 and a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 128, we end up with 128.
Bring next digit (6) of the dividend behind the 128 and repeat the process: 1286 / 674

On to step 4:
When dividing 1286 by 674, we get 1 with a remainder of 612.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 674 from 1286 to get 612.
Append the next digit (0) from the dividend to 612 and continue with: 6120 / 674

Let's proceed to step 5:
674 goes into 6120 9 times with a remainder of 54.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 54 after subtracting 6066 from 6120.
Fetch the next digit (2) from the dividend, attach it to 54 and continue: 542 / 674

Step 6:
When dividing 542 by 674, we get 0 with a remainder of 542.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
Subtracting 0 from 542 leaves us with 542.
Take the next digit (9) from the dividend and append it to 542, then repeat: 5429 / 674

Step 7:
5429 divided by 674 is 8 with a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 1908.0
Subtracting 5392 from 5429 leaves us with 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 674

Advancing to step 8:
374 divided by 674 is 0 with a remainder of 374.
Write down 0 as next digit of the result. 
Result so far: 19080.0
Subtracting 0 from 374 leaves us with 374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 9:
674 goes into 3740 5 times with a remainder of 370.
The next digit of our result is 5. 
Result so far: 19080.5
If we take 3370 away from 3740, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 10:
The number 674 fits into 3700 5 times, leaving a remainder of 330.
Use 5 as the next digit of our solution. 
Result so far: 19080.55
If we take 3370 away from 3700, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

The final result is 19080.55 with a remainder of 0.33.
