We're dividing 17639592 by 685 
We want to figure out the number of times 17639592 can be divided by 685.

Step 1:
When dividing 1 by 685, we get 0 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.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 685

Moving on to step 2:
685 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 685

Let's proceed to step 3:
When dividing 176 by 685, we get 0 with a remainder of 176.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 176 after subtracting 0 from 176.
Append the next digit (3) from the dividend to 176 and continue with: 1763 / 685

Going ahead to step 4:
If we divide 1763 by 685, we get 2 and a remainder of 393.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1370 from 1763 and we're left with 393.
Grab the next digit (9) from the dividend, add it to 393, then carry on: 3939 / 685

Going ahead to step 5:
685 goes into 3939 5 times with a remainder of 514.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 3425 from 3939 to get 514.
Include the next digit (5) from the dividend after 514, then repeat: 5145 / 685

Going ahead to step 6:
5145 divided by 685 is 7 with a remainder of 350.
Use 7 as the next digit of our solution. 
Result so far: 257.0
Subtracting 4795 from 5145 leaves us with 350.
Bring next digit (9) of the dividend behind the 350 and repeat the process: 3509 / 685

Step 7:
When dividing 3509 by 685, we get 5 with a remainder of 84.
Use 5 as the next digit of our solution. 
Result so far: 2575.0
If we subtract 3425 from 3509, we get 84.
Include the next digit (2) from the dividend after 84, then repeat: 842 / 685

Step 8:
842 divided by 685 is 1 with a remainder of 157.
Record the quotient 1 as the next digit in the result. 
Result so far: 25751.0
If we take 685 away from 842, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Let's proceed to step 9:
685 goes into 1570 2 times with a remainder of 200.
Put 2 as the next digit of the answer. 
Result so far: 25751.2
If we take 1370 away from 1570, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
When dividing 2000 by 685, we get 2 with a remainder of 630.
The number 2 becomes the next digit in our result. 
Result so far: 25751.22
If we subtract 1370 from 2000, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Our division results in 25751.22 with a remaining 0.63.
