We divide 261911 by 81
We want to divide 261911 by 81.

Moving on to step 1:
When dividing 2 by 81, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 81

Going ahead to step 2:
If we divide 26 by 81, we get 0 and a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 81

On to step 3:
The number 81 fits into 261 3 times, leaving a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 243 from 261 and we're left with 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 81

Let's proceed to step 4:
When dividing 189 by 81, we get 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 32.0
If we subtract 162 from 189, we get 27.
Fetch the next digit (1) from the dividend, attach it to 27 and continue: 271 / 81

Advancing to step 5:
The number 81 fits into 271 3 times, leaving a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 323.0
Deduct 243 from 271 and we're left with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 81

On to step 6:
81 can be fit into 281 3 times, resulting in a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 3233.0
Deduct 243 from 281 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
If we divide 380 by 81, we get 4 and a remainder of 56.
The next digit of our result is 4. 
Result so far: 3233.4
The remainder is 56 after subtracting 324 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
When dividing 560 by 81, we get 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 3233.46
The remainder is 74 after subtracting 486 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 9:
81 can be fit into 740 9 times, resulting in a remainder of 11.
The next digit of our result is 9. 
Result so far: 3233.469
Deduct 729 from 740 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 10:
110 divided by 81 is 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 3233.4691
Subtract 81 from 110 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
If we divide 290 by 81, we get 3 and a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 3233.46913
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 12:
When dividing 470 by 81, we get 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 3233.469135
If we subtract 405 from 470, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 13:
When dividing 650 by 81, we get 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 3233.4691358
The remainder is 2 after subtracting 648 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
When dividing 20 by 81, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 3233.4691358
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 3233.4691358 and a remainder of 2e-08.
