809442 divided by 81 
We want to divide 809442 by 81.

On to step 1:
When dividing 8 by 81, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 81

On to step 2:
81 goes into 80 0 times with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 80 leaves us with 80.
Grab the next digit (9) from the dividend, add it to 80, then carry on: 809 / 81

Let's proceed to step 3:
The number 81 fits into 809 9 times, leaving a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 729 from 809 to get 80.
Include the next digit (4) from the dividend after 80, then repeat: 804 / 81

Let's proceed to step 4:
When dividing 804 by 81, we get 9 with a remainder of 75.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we take 729 away from 804, we end up with 75.
Grab the next digit (4) from the dividend, add it to 75, then carry on: 754 / 81

Going ahead to step 5:
When dividing 754 by 81, we get 9 with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 999.0
If we take 729 away from 754, we end up with 25.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 81

Step 6:
If we divide 252 by 81, we get 3 and a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 9993.0
If we take 243 away from 252, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
81 can be fit into 90 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 9993.1
Deduct 81 from 90 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
90 divided by 81 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 9993.11
Subtracting 81 from 90 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 9993.11 and a remainder of 0.009.
