81490521 ÷ 844 
We're looking to find how many times 844 goes into 81490521.

Step 1:
When dividing 8 by 844, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 844

Step 2:
844 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (4) from the dividend, add it to 81, then carry on: 814 / 844

On to step 3:
When dividing 814 by 844, we get 0 with a remainder of 814.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 814 leaves us with 814.
Grab the next digit (9) from the dividend, add it to 814, then carry on: 8149 / 844

On to step 4:
When dividing 8149 by 844, we get 9 with a remainder of 553.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 7596 from 8149 leaves us with 553.
Include the next digit (0) from the dividend after 553, then repeat: 5530 / 844

Moving on to step 5:
844 goes into 5530 6 times with a remainder of 466.
The next digit of our result is 6. 
Result so far: 96.0
Subtract 5064 from 5530 to get 466.
Append the next digit (5) from the dividend to 466 and continue with: 4665 / 844

Step 6:
When dividing 4665 by 844, we get 5 with a remainder of 445.
Put 5 as the next digit of the answer. 
Result so far: 965.0
If we subtract 4220 from 4665, we get 445.
Fetch the next digit (2) from the dividend, attach it to 445 and continue: 4452 / 844

Let's proceed to step 7:
844 can be fit into 4452 5 times, resulting in a remainder of 232.
The next digit of our result is 5. 
Result so far: 9655.0
Deduct 4220 from 4452 and we're left with 232.
Append the next digit (1) from the dividend to 232 and continue with: 2321 / 844

Going ahead to step 8:
844 can be fit into 2321 2 times, resulting in a remainder of 633.
The number 2 becomes the next digit in our result. 
Result so far: 96552.0
Subtracting 1688 from 2321 leaves us with 633.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6330, and continue the process.

Going ahead to step 9:
If we divide 6330 by 844, we get 7 and a remainder of 422.
Put 7 as the next digit of the answer. 
Result so far: 96552.7
Deduct 5908 from 6330 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

Step 10:
The number 844 fits into 4220 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 96552.75
The remainder is 0 after subtracting 4220 from 4220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
844 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 96552.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
0 divided by 844 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 96552.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 96552.75 with a balance of 0.0.
