728378 ÷ 81 
Our goal is to divide 728378 by 81.

Advancing to step 1:
81 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 81

Let's proceed to step 2:
When dividing 72 by 81, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Fetch the next digit (8) from the dividend, attach it to 72 and continue: 728 / 81

Going ahead to step 3:
When dividing 728 by 81, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 648 from 728 to get 80.
Append the next digit (3) from the dividend to 80 and continue with: 803 / 81

Moving on to step 4:
The number 81 fits into 803 9 times, leaving a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 89.0
Subtract 729 from 803 to get 74.
Fetch the next digit (7) from the dividend, attach it to 74 and continue: 747 / 81

On to step 5:
81 goes into 747 9 times with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 899.0
Subtracting 729 from 747 leaves us with 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 81

Advancing to step 6:
81 goes into 188 2 times with a remainder of 26.
The next digit of our result is 2. 
Result so far: 8992.0
The remainder is 26 after subtracting 162 from 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
81 goes into 260 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 8992.3
If we take 243 away from 260, we end up 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.

Let's proceed to step 8:
When dividing 170 by 81, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 8992.32
Subtracting 162 from 170 leaves us 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 9:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 8992.32
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
When dividing 800 by 81, we get 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 8992.3209
The remainder is 71 after subtracting 729 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 11:
81 can be fit into 710 8 times, resulting in a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 8992.32098
Subtracting 648 from 710 leaves us 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.

Step 12:
When dividing 620 by 81, we get 7 with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 8992.320987
Subtracting 567 from 620 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 13:
81 can be fit into 530 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 8992.3209876
The remainder is 44 after subtracting 486 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
The number 81 fits into 440 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 8992.32098765
Subtracting 405 from 440 leaves us 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.

After the division, we end up with 8992.32098765 and a remainder of 3.5e-08.
