We divide 13305631 by 809
We want to divide 13305631 by 809.

Going ahead to step 1:
If we divide 1 by 809, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 809

Step 2:
The number 809 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 809

Going ahead to step 3:
809 goes into 133 0 times with a remainder of 133.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 133 leaves us with 133.
Fetch the next digit (0) from the dividend, attach it to 133 and continue: 1330 / 809

Step 4:
809 can be fit into 1330 1 times, resulting in a remainder of 521.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 809 from 1330 to get 521.
Bring next digit (5) of the dividend behind the 521 and repeat the process: 5215 / 809

On to step 5:
If we divide 5215 by 809, we get 6 and a remainder of 361.
The next digit of our result is 6. 
Result so far: 16.0
Deduct 4854 from 5215 and we're left with 361.
Bring next digit (6) of the dividend behind the 361 and repeat the process: 3616 / 809

Advancing to step 6:
The number 809 fits into 3616 4 times, leaving a remainder of 380.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtracting 3236 from 3616 leaves us with 380.
Include the next digit (3) from the dividend after 380, then repeat: 3803 / 809

Let's proceed to step 7:
809 can be fit into 3803 4 times, resulting in a remainder of 567.
The next digit of our result is 4. 
Result so far: 1644.0
The remainder is 567 after subtracting 3236 from 3803.
Bring next digit (1) of the dividend behind the 567 and repeat the process: 5671 / 809

Moving on to step 8:
809 can be fit into 5671 7 times, resulting in a remainder of 8.
The next digit of our result is 7. 
Result so far: 16447.0
If we take 5663 away from 5671, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 809 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 16447.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
809 goes into 800 0 times with a remainder of 800.
The number 0 becomes the next digit in our result. 
Result so far: 16447.0
If we take 0 away from 800, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Our division results in 16447.0 with a remaining 0.8.
