We look at the division of 3308351 by 809 
Let's see how many times 809 fits into 3308351.

Step 1:
When dividing 3 by 809, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 809

Going ahead to step 2:
When dividing 33 by 809, we get 0 with a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Include the next digit (0) from the dividend after 33, then repeat: 330 / 809

On to step 3:
The number 809 fits into 330 0 times, leaving a remainder of 330.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 330, we get 330.
Append the next digit (8) from the dividend to 330 and continue with: 3308 / 809

Going ahead to step 4:
If we divide 3308 by 809, we get 4 and a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 3236 from 3308, we get 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 809

Advancing to step 5:
809 goes into 723 0 times with a remainder of 723.
Write down 0 as next digit of the result. 
Result so far: 40.0
If we take 0 away from 723, we end up with 723.
Bring next digit (5) of the dividend behind the 723 and repeat the process: 7235 / 809

On to step 6:
The number 809 fits into 7235 8 times, leaving a remainder of 763.
Write down 8 as next digit of the result. 
Result so far: 408.0
Subtracting 6472 from 7235 leaves us with 763.
Append the next digit (1) from the dividend to 763 and continue with: 7631 / 809

Going ahead to step 7:
The number 809 fits into 7631 9 times, leaving a remainder of 350.
The next digit of our result is 9. 
Result so far: 4089.0
Subtract 7281 from 7631 to get 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 8:
809 can be fit into 3500 4 times, resulting in a remainder of 264.
Use 4 as the next digit of our solution. 
Result so far: 4089.4
If we subtract 3236 from 3500, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 9:
809 goes into 2640 3 times with a remainder of 213.
Use 3 as the next digit of our solution. 
Result so far: 4089.43
The remainder is 213 after subtracting 2427 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Going ahead to step 10:
The number 809 fits into 2130 2 times, leaving a remainder of 512.
Put 2 as the next digit of the answer. 
Result so far: 4089.432
Deduct 1618 from 2130 and we're left with 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 11:
809 can be fit into 5120 6 times, resulting in a remainder of 266.
Put 6 as the next digit of the answer. 
Result so far: 4089.4326
Subtracting 4854 from 5120 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 12:
2660 divided by 809 is 3 with a remainder of 233.
Record the quotient 3 as the next digit in the result. 
Result so far: 4089.43263
If we subtract 2427 from 2660, we get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 13:
If we divide 2330 by 809, we get 2 and a remainder of 712.
Write down 2 as next digit of the result. 
Result so far: 4089.432632
Deduct 1618 from 2330 and we're left with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Moving on to step 14:
7120 divided by 809 is 8 with a remainder of 648.
Write down 8 as next digit of the result. 
Result so far: 4089.4326328
Subtract 6472 from 7120 to get 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Step 15:
6480 divided by 809 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 4089.43263288
If we subtract 6472 from 6480, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 4089.43263288, with a leftover of 8e-09.
