We divide 810009 by 81
We want to divide 810009 by 81.

Let's proceed to step 1:
81 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 81

Let's proceed to step 2:
81 divided by 81 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 81 from 81, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 81

Step 3:
0 divided by 81 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 81

Step 4:
0 divided by 81 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 0 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 81

Step 5:
The number 81 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1000.0
Subtract 0 from 0 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 81

Step 6:
81 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 10000.0
Subtract 0 from 9 to get 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 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: 10000.1
If we subtract 81 from 90, we get 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 8:
81 goes into 90 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 10000.11
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.

In conclusion, the division gives 10000.11 with a balance of 0.009.
