36447621 divided by 81 
We want to divide 36447621 by 81.

Going ahead to step 1:
If we divide 3 by 81, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 81

Step 2:
81 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 81

Moving on to step 3:
When dividing 364 by 81, we get 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 4.0
If we take 324 away from 364, we end up with 40.
Include the next digit (4) from the dividend after 40, then repeat: 404 / 81

Advancing to step 4:
404 divided by 81 is 4 with a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 324 from 404, we get 80.
Grab the next digit (7) from the dividend, add it to 80, then carry on: 807 / 81

Step 5:
807 divided by 81 is 9 with a remainder of 78.
Record the quotient 9 as the next digit in the result. 
Result so far: 449.0
Subtracting 729 from 807 leaves us with 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 81

Advancing to step 6:
786 divided by 81 is 9 with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 4499.0
Deduct 729 from 786 and we're left with 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 81

Let's proceed to step 7:
572 divided by 81 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 44997.0
The remainder is 5 after subtracting 567 from 572.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 81

Moving on to step 8:
The number 81 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 449970.0
The remainder is 51 after subtracting 0 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
81 goes into 510 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 449970.6
The remainder is 24 after subtracting 486 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 10:
The number 81 fits into 240 2 times, leaving a remainder of 78.
Use 2 as the next digit of our solution. 
Result so far: 449970.62
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 11:
The number 81 fits into 780 9 times, leaving a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 449970.629
The remainder is 51 after subtracting 729 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 12:
If we divide 510 by 81, we get 6 and a remainder of 24.
The next digit of our result is 6. 
Result so far: 449970.6296
If we take 486 away from 510, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
If we divide 240 by 81, we get 2 and a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 449970.62962
If we subtract 162 from 240, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 14:
The number 81 fits into 780 9 times, leaving a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 449970.629629
Subtract 729 from 780 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 15:
The number 81 fits into 510 6 times, leaving a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 449970.6296296
If we subtract 486 from 510, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 16:
81 goes into 240 2 times with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 449970.62962962
The remainder is 78 after subtracting 162 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final result is 449970.62962962 with a remainder of 7.8e-08.
