We look at the division of 8080511 by 638 
We want to divide 8080511 by 638.

Going ahead to step 1:
8 divided by 638 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 638

Moving on to step 2:
638 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 80 after subtracting 0 from 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 638

Advancing to step 3:
638 goes into 808 1 times with a remainder of 170.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 638 from 808 and we're left with 170.
Grab the next digit (0) from the dividend, add it to 170, then carry on: 1700 / 638

Let's proceed to step 4:
The number 638 fits into 1700 2 times, leaving a remainder of 424.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 424 after subtracting 1276 from 1700.
Take the next digit (5) from the dividend and append it to 424, then repeat: 4245 / 638

Moving on to step 5:
If we divide 4245 by 638, we get 6 and a remainder of 417.
The next digit of our result is 6. 
Result so far: 126.0
Subtracting 3828 from 4245 leaves us with 417.
Include the next digit (1) from the dividend after 417, then repeat: 4171 / 638

Going ahead to step 6:
If we divide 4171 by 638, we get 6 and a remainder of 343.
Write down 6 as next digit of the result. 
Result so far: 1266.0
If we subtract 3828 from 4171, we get 343.
Fetch the next digit (1) from the dividend, attach it to 343 and continue: 3431 / 638

Let's proceed to step 7:
3431 divided by 638 is 5 with a remainder of 241.
The next digit of our result is 5. 
Result so far: 12665.0
Subtract 3190 from 3431 to get 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2410, and continue the process.

Step 8:
When dividing 2410 by 638, we get 3 with a remainder of 496.
The next digit of our result is 3. 
Result so far: 12665.3
The remainder is 496 after subtracting 1914 from 2410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 9:
638 can be fit into 4960 7 times, resulting in a remainder of 494.
Put 7 as the next digit of the answer. 
Result so far: 12665.37
If we take 4466 away from 4960, we end up with 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 10:
The number 638 fits into 4940 7 times, leaving a remainder of 474.
The next digit of our result is 7. 
Result so far: 12665.377
The remainder is 474 after subtracting 4466 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Our division results in 12665.377 with a remaining 0.0474.
