Let's divide 81624409 by 900
Our goal is to divide 81624409 by 900.

Moving on to step 1:
The number 900 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 900

Going ahead to step 2:
900 can be fit into 81 0 times, resulting in a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Append the next digit (6) from the dividend to 81 and continue with: 816 / 900

Step 3:
816 divided by 900 is 0 with a remainder of 816.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 816, we get 816.
Include the next digit (2) from the dividend after 816, then repeat: 8162 / 900

Let's proceed to step 4:
If we divide 8162 by 900, we get 9 and a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 8100 from 8162 to get 62.
Grab the next digit (4) from the dividend, add it to 62, then carry on: 624 / 900

Moving on to step 5:
If we divide 624 by 900, we get 0 and a remainder of 624.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Deduct 0 from 624 and we're left with 624.
Grab the next digit (4) from the dividend, add it to 624, then carry on: 6244 / 900

Advancing to step 6:
900 can be fit into 6244 6 times, resulting in a remainder of 844.
Record the quotient 6 as the next digit in the result. 
Result so far: 906.0
If we subtract 5400 from 6244, we get 844.
Include the next digit (0) from the dividend after 844, then repeat: 8440 / 900

Let's proceed to step 7:
8440 divided by 900 is 9 with a remainder of 340.
Record the quotient 9 as the next digit in the result. 
Result so far: 9069.0
If we subtract 8100 from 8440, we get 340.
Bring next digit (9) of the dividend behind the 340 and repeat the process: 3409 / 900

Step 8:
When dividing 3409 by 900, we get 3 with a remainder of 709.
Use 3 as the next digit of our solution. 
Result so far: 90693.0
Deduct 2700 from 3409 and we're left with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

On to step 9:
7090 divided by 900 is 7 with a remainder of 790.
Put 7 as the next digit of the answer. 
Result so far: 90693.7
If we subtract 6300 from 7090, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Going ahead to step 10:
The number 900 fits into 7900 8 times, leaving a remainder of 700.
Put 8 as the next digit of the answer. 
Result so far: 90693.78
Deduct 7200 from 7900 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 11:
900 can be fit into 7000 7 times, resulting in a remainder of 700.
Record the quotient 7 as the next digit in the result. 
Result so far: 90693.787
Deduct 6300 from 7000 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Let's proceed to step 12:
The number 900 fits into 7000 7 times, leaving a remainder of 700.
The next digit of our result is 7. 
Result so far: 90693.7877
If we take 6300 away from 7000, we end up with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

In conclusion, the division gives 90693.7877 with a balance of 0.007.
