457829 ÷ 81 
Our goal is to divide 457829 by 81.

Step 1:
4 divided by 81 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 81

On to step 2:
45 divided by 81 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Take the next digit (7) from the dividend and append it to 45, then repeat: 457 / 81

Going ahead to step 3:
81 goes into 457 5 times with a remainder of 52.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 405 from 457 leaves us with 52.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 81

Advancing to step 4:
The number 81 fits into 528 6 times, leaving a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
If we take 486 away from 528, we end up with 42.
Append the next digit (2) from the dividend to 42 and continue with: 422 / 81

Going ahead to step 5:
422 divided by 81 is 5 with a remainder of 17.
Put 5 as the next digit of the answer. 
Result so far: 565.0
The remainder is 17 after subtracting 405 from 422.
Grab the next digit (9) from the dividend, add it to 17, then carry on: 179 / 81

Advancing to step 6:
If we divide 179 by 81, we get 2 and a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 5652.0
Subtracting 162 from 179 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
81 goes into 170 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 5652.2
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
80 divided by 81 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 5652.2
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 9:
If we divide 800 by 81, we get 9 and a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 5652.209
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.

Going ahead to step 10:
When dividing 710 by 81, we get 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 5652.2098
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.

Advancing to step 11:
620 divided by 81 is 7 with a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 5652.20987
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 12:
81 can be fit into 530 6 times, resulting in a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 5652.209876
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 13:
When dividing 440 by 81, we get 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 5652.2098765
If we take 405 away from 440, we end up with 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 14:
350 divided by 81 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 5652.20987654
The remainder is 26 after subtracting 324 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 5652.20987654 with a remainder of 2.6e-08.
