We look at the division of 275398 by 81 
Let's see how many times 81 fits into 275398.

Step 1:
When dividing 2 by 81, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 81

Step 2:
81 can be fit into 27 0 times, resulting in a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 27 leaves us with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 81

Going ahead to step 3:
275 divided by 81 is 3 with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 243 from 275 to get 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 81

Going ahead to step 4:
If we divide 323 by 81, we get 3 and a remainder of 80.
The next digit of our result is 3. 
Result so far: 33.0
If we take 243 away from 323, we end up with 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 81

Moving on to step 5:
If we divide 809 by 81, we get 9 and a remainder of 80.
The next digit of our result is 9. 
Result so far: 339.0
If we subtract 729 from 809, we get 80.
Take the next digit (8) from the dividend and append it to 80, then repeat: 808 / 81

Let's proceed to step 6:
81 can be fit into 808 9 times, resulting in a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 3399.0
If we take 729 away from 808, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 7:
The number 81 fits into 790 9 times, leaving a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 3399.9
Subtracting 729 from 790 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 8:
The number 81 fits into 610 7 times, leaving a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 3399.97
If we take 567 away from 610, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 9:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 3399.975
Subtract 405 from 430 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 3399.9753
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
70 divided by 81 is 0 with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 3399.9753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
The number 81 fits into 700 8 times, leaving a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 3399.975308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 13:
520 divided by 81 is 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 3399.9753086
Subtracting 486 from 520 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 14:
81 can be fit into 340 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 3399.97530864
Subtracting 324 from 340 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 3399.97530864 with a remaining 1.6e-08.
