We look at the division of 41405280 by 81 
Let's see how many times 81 fits into 41405280.

On to step 1:
4 divided by 81 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 81

Step 2:
81 goes into 41 0 times with a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 41 to get 41.
Include the next digit (4) from the dividend after 41, then repeat: 414 / 81

Advancing to step 3:
414 divided by 81 is 5 with a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 405 from 414 leaves us with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 81

Going ahead to step 4:
81 goes into 90 1 times with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we take 81 away from 90, we end up with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 81

Moving on to step 5:
When dividing 95 by 81, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 511.0
If we subtract 81 from 95, we get 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 81

Advancing to step 6:
When dividing 142 by 81, we get 1 with a remainder of 61.
Write down 1 as next digit of the result. 
Result so far: 5111.0
If we subtract 81 from 142, we get 61.
Grab the next digit (8) from the dividend, add it to 61, then carry on: 618 / 81

Going ahead to step 7:
81 goes into 618 7 times with a remainder of 51.
Put 7 as the next digit of the answer. 
Result so far: 51117.0
The remainder is 51 after subtracting 567 from 618.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 81

Moving on to step 8:
510 divided by 81 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 511176.0
Subtracting 486 from 510 leaves us 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 9:
81 can be fit into 240 2 times, resulting in a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 511176.2
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.

On to step 10:
81 goes into 780 9 times with a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 511176.29
Subtracting 729 from 780 leaves us with 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 11:
81 can be fit into 510 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 511176.296
Subtracting 486 from 510 leaves us 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.

Step 12:
When dividing 240 by 81, we get 2 with a remainder of 78.
The next digit of our result is 2. 
Result so far: 511176.2962
Subtracting 162 from 240 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 13:
The number 81 fits into 780 9 times, leaving a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 511176.29629
Deduct 729 from 780 and we're left with 51.
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 14:
When dividing 510 by 81, we get 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 511176.296296
Subtract 486 from 510 to 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 15:
If we divide 240 by 81, we get 2 and a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 511176.2962962
If we take 162 away from 240, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 16:
If we divide 780 by 81, we get 9 and a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 511176.29629629
Deduct 729 from 780 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

The final result is 511176.29629629 with a remainder of 5.1e-08.
