We look at the division of 9863915 by 808 
We're looking to find how many times 808 goes into 9863915.

On to step 1:
9 divided by 808 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 808

Let's proceed to step 2:
If we divide 98 by 808, we get 0 and a remainder of 98.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 98 after subtracting 0 from 98.
Grab the next digit (6) from the dividend, add it to 98, then carry on: 986 / 808

Moving on to step 3:
If we divide 986 by 808, we get 1 and a remainder of 178.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 808 from 986, we get 178.
Grab the next digit (3) from the dividend, add it to 178, then carry on: 1783 / 808

On to step 4:
When dividing 1783 by 808, we get 2 with a remainder of 167.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 1616 from 1783, we get 167.
Fetch the next digit (9) from the dividend, attach it to 167 and continue: 1679 / 808

Step 5:
808 can be fit into 1679 2 times, resulting in a remainder of 63.
Use 2 as the next digit of our solution. 
Result so far: 122.0
Subtract 1616 from 1679 to get 63.
Include the next digit (1) from the dividend after 63, then repeat: 631 / 808

Moving on to step 6:
808 goes into 631 0 times with a remainder of 631.
Put 0 as the next digit of the answer. 
Result so far: 1220.0
Subtract 0 from 631 to get 631.
Include the next digit (5) from the dividend after 631, then repeat: 6315 / 808

On to step 7:
808 can be fit into 6315 7 times, resulting in a remainder of 659.
The next digit of our result is 7. 
Result so far: 12207.0
Deduct 5656 from 6315 and we're left with 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6590, and continue the process.

Going ahead to step 8:
6590 divided by 808 is 8 with a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 12207.8
If we take 6464 away from 6590, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 9:
1260 divided by 808 is 1 with a remainder of 452.
The next digit of our result is 1. 
Result so far: 12207.81
Subtract 808 from 1260 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Advancing to step 10:
When dividing 4520 by 808, we get 5 with a remainder of 480.
The number 5 becomes the next digit in our result. 
Result so far: 12207.815
The remainder is 480 after subtracting 4040 from 4520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 11:
808 can be fit into 4800 5 times, resulting in a remainder of 760.
Put 5 as the next digit of the answer. 
Result so far: 12207.8155
Subtract 4040 from 4800 to get 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

The quotient of the division is 12207.8155, and the remainder is 0.0076.
