We're dividing 408315 by 81 
We want to divide 408315 by 81.

Let's proceed to step 1:
4 divided by 81 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 81

Going ahead to step 2:
81 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 81

Step 3:
When dividing 408 by 81, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 405 from 408 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 81

Going ahead to step 4:
If we divide 33 by 81, we get 0 and a remainder of 33.
Write down 0 as next digit of the result. 
Result so far: 50.0
If we subtract 0 from 33, we get 33.
Take the next digit (1) from the dividend and append it to 33, then repeat: 331 / 81

On to step 5:
81 can be fit into 331 4 times, resulting in a remainder of 7.
The next digit of our result is 4. 
Result so far: 504.0
Subtracting 324 from 331 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 81

Moving on to step 6:
81 goes into 75 0 times with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 5040.0
The remainder is 75 after subtracting 0 from 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 7:
81 goes into 750 9 times with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 5040.9
Deduct 729 from 750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
81 can be fit into 210 2 times, resulting in a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 5040.92
Subtract 162 from 210 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
81 can be fit into 480 5 times, resulting in a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 5040.925
If we subtract 405 from 480, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 10:
81 goes into 750 9 times with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 5040.9259
Subtracting 729 from 750 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
When dividing 210 by 81, we get 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 5040.92592
If we subtract 162 from 210, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 12:
If we divide 480 by 81, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 5040.925925
Subtract 405 from 480 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 13:
When dividing 750 by 81, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 5040.9259259
Subtract 729 from 750 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 14:
When dividing 210 by 81, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 5040.92592592
If we subtract 162 from 210, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 5040.92592592 with a remaining 4.8e-08.
