We look at the division of 15257866 by 744 
We want to divide 15257866 by 744.

Let's proceed to step 1:
744 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 744

Step 2:
15 divided by 744 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 744

Step 3:
744 can be fit into 152 0 times, resulting in a remainder of 152.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 152, we end up with 152.
Fetch the next digit (5) from the dividend, attach it to 152 and continue: 1525 / 744

Let's proceed to step 4:
The number 744 fits into 1525 2 times, leaving a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1488 away from 1525, we end up with 37.
Include the next digit (7) from the dividend after 37, then repeat: 377 / 744

Let's proceed to step 5:
744 goes into 377 0 times with a remainder of 377.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 377 and we're left with 377.
Include the next digit (8) from the dividend after 377, then repeat: 3778 / 744

Advancing to step 6:
3778 divided by 744 is 5 with a remainder of 58.
Write down 5 as next digit of the result. 
Result so far: 205.0
Subtracting 3720 from 3778 leaves us with 58.
Take the next digit (6) from the dividend and append it to 58, then repeat: 586 / 744

Step 7:
When dividing 586 by 744, we get 0 with a remainder of 586.
Record the quotient 0 as the next digit in the result. 
Result so far: 2050.0
Subtracting 0 from 586 leaves us with 586.
Grab the next digit (6) from the dividend, add it to 586, then carry on: 5866 / 744

Going ahead to step 8:
5866 divided by 744 is 7 with a remainder of 658.
Write down 7 as next digit of the result. 
Result so far: 20507.0
If we subtract 5208 from 5866, we get 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

On to step 9:
6580 divided by 744 is 8 with a remainder of 628.
Use 8 as the next digit of our solution. 
Result so far: 20507.8
Subtracting 5952 from 6580 leaves us with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 10:
If we divide 6280 by 744, we get 8 and a remainder of 328.
The number 8 becomes the next digit in our result. 
Result so far: 20507.88
If we subtract 5952 from 6280, we get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Our division results in 20507.88 with a remaining 0.328.
