We look at the division of 65723878 by 809 
Let's see how many times 809 fits into 65723878.

Advancing to step 1:
6 divided by 809 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 809

Advancing to step 2:
When dividing 65 by 809, we get 0 with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 809

On to step 3:
The number 809 fits into 657 0 times, leaving a remainder of 657.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 657, we get 657.
Bring next digit (2) of the dividend behind the 657 and repeat the process: 6572 / 809

Step 4:
When dividing 6572 by 809, we get 8 with a remainder of 100.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 6472 from 6572 leaves us with 100.
Take the next digit (3) from the dividend and append it to 100, then repeat: 1003 / 809

Let's proceed to step 5:
809 can be fit into 1003 1 times, resulting in a remainder of 194.
Use 1 as the next digit of our solution. 
Result so far: 81.0
If we take 809 away from 1003, we end up with 194.
Bring next digit (8) of the dividend behind the 194 and repeat the process: 1948 / 809

Step 6:
The number 809 fits into 1948 2 times, leaving a remainder of 330.
The next digit of our result is 2. 
Result so far: 812.0
If we take 1618 away from 1948, we end up with 330.
Fetch the next digit (7) from the dividend, attach it to 330 and continue: 3307 / 809

Going ahead to step 7:
When dividing 3307 by 809, we get 4 with a remainder of 71.
The number 4 becomes the next digit in our result. 
Result so far: 8124.0
If we take 3236 away from 3307, we end up with 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 809

Let's proceed to step 8:
718 divided by 809 is 0 with a remainder of 718.
Write down 0 as next digit of the result. 
Result so far: 81240.0
Subtract 0 from 718 to get 718.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7180, and continue the process.

Going ahead to step 9:
If we divide 7180 by 809, we get 8 and a remainder of 708.
Write down 8 as next digit of the result. 
Result so far: 81240.8
If we take 6472 away from 7180, we end up with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Step 10:
The number 809 fits into 7080 8 times, leaving a remainder of 608.
Record the quotient 8 as the next digit in the result. 
Result so far: 81240.88
Subtract 6472 from 7080 to get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Our division results in 81240.88 with a remaining 0.608.
