391481 divided by 81 
Our goal is to divide 391481 by 81.

Moving on to step 1:
3 divided by 81 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 81

Advancing to step 2:
When dividing 39 by 81, we get 0 with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 81

Advancing to step 3:
81 can be fit into 391 4 times, resulting in a remainder of 67.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 324 from 391 and we're left with 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 81

Step 4:
If we divide 674 by 81, we get 8 and a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we subtract 648 from 674, we get 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 81

Going ahead to step 5:
81 can be fit into 268 3 times, resulting in a remainder of 25.
Use 3 as the next digit of our solution. 
Result so far: 483.0
If we subtract 243 from 268, we get 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 81

On to step 6:
251 divided by 81 is 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 4833.0
If we subtract 243 from 251, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
When dividing 80 by 81, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 4833.0
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
If we divide 800 by 81, we get 9 and a remainder of 71.
Put 9 as the next digit of the answer. 
Result so far: 4833.09
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
The number 81 fits into 710 8 times, leaving a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 4833.098
Deduct 648 from 710 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
If we divide 620 by 81, we get 7 and a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 4833.0987
If we subtract 567 from 620, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 11:
530 divided by 81 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 4833.09876
If we take 486 away from 530, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 4833.098765
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
If we divide 350 by 81, we get 4 and a remainder of 26.
The next digit of our result is 4. 
Result so far: 4833.0987654
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
When dividing 260 by 81, we get 3 with a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 4833.09876543
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 4833.09876543 with a remaining 1.7e-08.
