We look at the division of 27618946 by 638 
Let's see how many times 638 fits into 27618946.

Moving on to step 1:
2 divided by 638 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 638

Advancing to step 2:
The number 638 fits into 27 0 times, leaving a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 638

Going ahead to step 3:
638 goes into 276 0 times with a remainder of 276.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 276 and we're left with 276.
Append the next digit (1) from the dividend to 276 and continue with: 2761 / 638

Let's proceed to step 4:
638 can be fit into 2761 4 times, resulting in a remainder of 209.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 2552 away from 2761, we end up with 209.
Bring next digit (8) of the dividend behind the 209 and repeat the process: 2098 / 638

Step 5:
The number 638 fits into 2098 3 times, leaving a remainder of 184.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtracting 1914 from 2098 leaves us with 184.
Bring next digit (9) of the dividend behind the 184 and repeat the process: 1849 / 638

Going ahead to step 6:
The number 638 fits into 1849 2 times, leaving a remainder of 573.
Write down 2 as next digit of the result. 
Result so far: 432.0
Subtracting 1276 from 1849 leaves us with 573.
Take the next digit (4) from the dividend and append it to 573, then repeat: 5734 / 638

On to step 7:
638 goes into 5734 8 times with a remainder of 630.
The number 8 becomes the next digit in our result. 
Result so far: 4328.0
Subtracting 5104 from 5734 leaves us with 630.
Grab the next digit (6) from the dividend, add it to 630, then carry on: 6306 / 638

Advancing to step 8:
The number 638 fits into 6306 9 times, leaving a remainder of 564.
Write down 9 as next digit of the result. 
Result so far: 43289.0
If we subtract 5742 from 6306, we get 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

On to step 9:
The number 638 fits into 5640 8 times, leaving a remainder of 536.
Write down 8 as next digit of the result. 
Result so far: 43289.8
Deduct 5104 from 5640 and we're left with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Step 10:
When dividing 5360 by 638, we get 8 with a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 43289.88
If we take 5104 away from 5360, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

The final result is 43289.88 with a remainder of 0.256.
