We look at the division of 9917886 by 808 
Let's see how many times 808 fits into 9917886.

Advancing to step 1:
808 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 808

On to step 2:
808 can be fit into 99 0 times, resulting in a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Fetch the next digit (1) from the dividend, attach it to 99 and continue: 991 / 808

Let's proceed to step 3:
The number 808 fits into 991 1 times, leaving a remainder of 183.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 808 from 991 and we're left with 183.
Take the next digit (7) from the dividend and append it to 183, then repeat: 1837 / 808

Step 4:
When dividing 1837 by 808, we get 2 with a remainder of 221.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 1616 from 1837, we get 221.
Include the next digit (8) from the dividend after 221, then repeat: 2218 / 808

Moving on to step 5:
If we divide 2218 by 808, we get 2 and a remainder of 602.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we take 1616 away from 2218, we end up with 602.
Include the next digit (8) from the dividend after 602, then repeat: 6028 / 808

Advancing to step 6:
808 goes into 6028 7 times with a remainder of 372.
The number 7 becomes the next digit in our result. 
Result so far: 1227.0
If we take 5656 away from 6028, we end up with 372.
Include the next digit (6) from the dividend after 372, then repeat: 3726 / 808

Moving on to step 7:
If we divide 3726 by 808, we get 4 and a remainder of 494.
Write down 4 as next digit of the result. 
Result so far: 12274.0
If we take 3232 away from 3726, 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.

Let's proceed to step 8:
If we divide 4940 by 808, we get 6 and a remainder of 92.
Write down 6 as next digit of the result. 
Result so far: 12274.6
Subtract 4848 from 4940 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 9:
808 goes into 920 1 times with a remainder of 112.
Put 1 as the next digit of the answer. 
Result so far: 12274.61
If we take 808 away from 920, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
The number 808 fits into 1120 1 times, leaving a remainder of 312.
Record the quotient 1 as the next digit in the result. 
Result so far: 12274.611
Subtract 808 from 1120 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Our division results in 12274.611 with a remaining 0.0312.
