We look at the division of 63663695 by 809 
Let's see how many times 809 fits into 63663695.

Going ahead to step 1:
The number 809 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 809

On to step 2:
If we divide 63 by 809, we get 0 and a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (6) from the dividend to 63 and continue with: 636 / 809

Going ahead to step 3:
If we divide 636 by 809, we get 0 and a remainder of 636.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 636 leaves us with 636.
Grab the next digit (6) from the dividend, add it to 636, then carry on: 6366 / 809

Going ahead to step 4:
When dividing 6366 by 809, we get 7 with a remainder of 703.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 5663 from 6366 leaves us with 703.
Fetch the next digit (3) from the dividend, attach it to 703 and continue: 7033 / 809

Moving on to step 5:
When dividing 7033 by 809, we get 8 with a remainder of 561.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we take 6472 away from 7033, we end up with 561.
Include the next digit (6) from the dividend after 561, then repeat: 5616 / 809

Step 6:
When dividing 5616 by 809, we get 6 with a remainder of 762.
The number 6 becomes the next digit in our result. 
Result so far: 786.0
If we take 4854 away from 5616, we end up with 762.
Take the next digit (9) from the dividend and append it to 762, then repeat: 7629 / 809

Going ahead to step 7:
7629 divided by 809 is 9 with a remainder of 348.
Write down 9 as next digit of the result. 
Result so far: 7869.0
If we subtract 7281 from 7629, we get 348.
Include the next digit (5) from the dividend after 348, then repeat: 3485 / 809

Going ahead to step 8:
809 goes into 3485 4 times with a remainder of 249.
The next digit of our result is 4. 
Result so far: 78694.0
Deduct 3236 from 3485 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 9:
The number 809 fits into 2490 3 times, leaving a remainder of 63.
Use 3 as the next digit of our solution. 
Result so far: 78694.3
If we subtract 2427 from 2490, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 10:
If we divide 630 by 809, we get 0 and a remainder of 630.
The next digit of our result is 0. 
Result so far: 78694.3
If we subtract 0 from 630, 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.

Let's proceed to step 11:
If we divide 6300 by 809, we get 7 and a remainder of 637.
The number 7 becomes the next digit in our result. 
Result so far: 78694.307
If we subtract 5663 from 6300, we get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Going ahead to step 12:
809 can be fit into 6370 7 times, resulting in a remainder of 707.
Put 7 as the next digit of the answer. 
Result so far: 78694.3077
Subtract 5663 from 6370 to get 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

After the division, we end up with 78694.3077 and a remainder of 0.00707.
