We're dividing 431582 by 81 
Our goal is to divide 431582 by 81.

Moving on to step 1:
4 divided by 81 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 81

Going ahead to step 2:
The number 81 fits into 43 0 times, leaving a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 43 after subtracting 0 from 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 81

Let's proceed to step 3:
When dividing 431 by 81, we get 5 with a remainder of 26.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 405 from 431 and we're left with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 81

On to step 4:
81 can be fit into 265 3 times, resulting in a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 53.0
Deduct 243 from 265 and we're left with 22.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 81

Moving on to step 5:
81 goes into 228 2 times with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 532.0
Deduct 162 from 228 and we're left with 66.
Include the next digit (2) from the dividend after 66, then repeat: 662 / 81

Moving on to step 6:
If we divide 662 by 81, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 5328.0
Subtract 648 from 662 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 81 is 1 with a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 5328.1
If we subtract 81 from 140, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 8:
When dividing 590 by 81, we get 7 with a remainder of 23.
Write down 7 as next digit of the result. 
Result so far: 5328.17
The remainder is 23 after subtracting 567 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 9:
81 goes into 230 2 times with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 5328.172
If we subtract 162 from 230, we get 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 10:
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: 5328.1728
Subtracting 648 from 680 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
81 goes into 320 3 times with a remainder of 77.
Record the quotient 3 as the next digit in the result. 
Result so far: 5328.17283
Subtract 243 from 320 to 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.

On to step 12:
770 divided by 81 is 9 with a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 5328.172839
If we take 729 away from 770, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 13:
The number 81 fits into 410 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5328.1728395
Subtracting 405 from 410 leaves us 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.

Let's proceed to step 14:
The number 81 fits into 50 0 times, leaving a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 5328.1728395
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 5328.1728395 with a remainder of 5e-08.
