We're dividing 12030440 by 81 
We want to divide 12030440 by 81.

Let's proceed to step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 81

Moving on to step 2:
When dividing 12 by 81, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 81

On to step 3:
81 can be fit into 120 1 times, resulting in a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 81 from 120, we get 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 81

Moving on to step 4:
81 goes into 393 4 times with a remainder of 69.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 69 after subtracting 324 from 393.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 81

Advancing to step 5:
The number 81 fits into 690 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 148.0
If we subtract 648 from 690, we get 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 81

Going ahead to step 6:
81 can be fit into 424 5 times, resulting in a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 1485.0
If we take 405 away from 424, we end up with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 81

Going ahead to step 7:
When dividing 194 by 81, we get 2 with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 14852.0
The remainder is 32 after subtracting 162 from 194.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 81

Moving on to step 8:
81 goes into 320 3 times with a remainder of 77.
The next digit of our result is 3. 
Result so far: 148523.0
If we subtract 243 from 320, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 9:
If we divide 770 by 81, we get 9 and a remainder of 41.
The next digit of our result is 9. 
Result so far: 148523.9
If we subtract 729 from 770, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 10:
410 divided by 81 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 148523.95
Deduct 405 from 410 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
If we divide 50 by 81, we get 0 and a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 148523.95
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
81 goes into 500 6 times with a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 148523.9506
The remainder is 14 after subtracting 486 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
140 divided by 81 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 148523.95061
If we take 81 away from 140, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 14:
590 divided by 81 is 7 with a remainder of 23.
The number 7 becomes the next digit in our result. 
Result so far: 148523.950617
Subtracting 567 from 590 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 15:
If we divide 230 by 81, we get 2 and a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 148523.9506172
If we take 162 away from 230, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 16:
If we divide 680 by 81, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 148523.95061728
Subtract 648 from 680 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 148523.95061728 with a remaining 3.2e-08.
