268658 ÷ 81 
Our goal is to divide 268658 by 81.

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
Subtracting 0 from 2 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 81

On to step 2:
The number 81 fits into 26 0 times, leaving a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 81

Advancing to step 3:
81 goes into 268 3 times with a remainder of 25.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 243 from 268, we get 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 81

Going ahead to step 4:
The number 81 fits into 256 3 times, leaving a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we subtract 243 from 256, we get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 81

Going ahead to step 5:
The number 81 fits into 135 1 times, leaving a remainder of 54.
The next digit of our result is 1. 
Result so far: 331.0
Subtract 81 from 135 to get 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 81

Moving on to step 6:
When dividing 548 by 81, we get 6 with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 3316.0
If we take 486 away from 548, we end up 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.

Going ahead to step 7:
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: 3316.7
If we take 567 away from 620, we end up 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 8:
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: 3316.76
If we subtract 486 from 530, we 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.

Advancing to step 9:
440 divided by 81 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 3316.765
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
When dividing 350 by 81, we get 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 3316.7654
Subtract 324 from 350 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
81 can be fit into 260 3 times, resulting in a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 3316.76543
Deduct 243 from 260 and we're left 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.

Moving on to step 12:
If we divide 170 by 81, we get 2 and a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 3316.765432
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.

Going ahead to step 13:
The number 81 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 3316.765432
If we subtract 0 from 80, we 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.

Moving on to step 14:
81 goes into 800 9 times with a remainder of 71.
The next digit of our result is 9. 
Result so far: 3316.76543209
Deduct 729 from 800 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 3316.76543209 and a remainder of 7.1e-08.
