We divide 311723 by 81
We want to figure out the number of times 311723 can be divided by 81.

On to step 1:
3 divided by 81 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 81

Moving on to step 2:
81 goes into 31 0 times with a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (1) from the dividend, attach it to 31 and continue: 311 / 81

Advancing to step 3:
81 can be fit into 311 3 times, resulting in a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 68 after subtracting 243 from 311.
Bring next digit (7) of the dividend behind the 68 and repeat the process: 687 / 81

On to step 4:
The number 81 fits into 687 8 times, leaving a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 38.0
Subtract 648 from 687 to get 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 81

Let's proceed to step 5:
81 can be fit into 392 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 384.0
Subtract 324 from 392 to get 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 81

Advancing to step 6:
683 divided by 81 is 8 with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 3848.0
Subtract 648 from 683 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.

On to step 7:
350 divided by 81 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 3848.4
Deduct 324 from 350 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 8:
81 can be fit into 260 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 3848.43
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
81 goes into 170 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 3848.432
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 10:
81 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 3848.432
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.

Going ahead to step 11:
When dividing 800 by 81, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 3848.43209
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.

Moving on to step 12:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 3848.432098
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 13:
81 can be fit into 620 7 times, resulting in a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 3848.4320987
Deduct 567 from 620 and we're left 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.

On to step 14:
The number 81 fits into 530 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 3848.43209876
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.

After the division, we end up with 3848.43209876 and a remainder of 4.4e-08.
