We're dividing 81023180 by 311 
We want to divide 81023180 by 311.

Moving on to step 1:
8 divided by 311 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 311

Advancing to step 2:
311 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Bring next digit (0) of the dividend behind the 81 and repeat the process: 810 / 311

Going ahead to step 3:
311 can be fit into 810 2 times, resulting in a remainder of 188.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 622 from 810, we get 188.
Grab the next digit (2) from the dividend, add it to 188, then carry on: 1882 / 311

On to step 4:
1882 divided by 311 is 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 26.0
If we subtract 1866 from 1882, we get 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 311

Moving on to step 5:
If we divide 163 by 311, we get 0 and a remainder of 163.
Write down 0 as next digit of the result. 
Result so far: 260.0
Subtract 0 from 163 to get 163.
Grab the next digit (1) from the dividend, add it to 163, then carry on: 1631 / 311

On to step 6:
311 can be fit into 1631 5 times, resulting in a remainder of 76.
Put 5 as the next digit of the answer. 
Result so far: 2605.0
The remainder is 76 after subtracting 1555 from 1631.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 311

Advancing to step 7:
The number 311 fits into 768 2 times, leaving a remainder of 146.
The number 2 becomes the next digit in our result. 
Result so far: 26052.0
Subtract 622 from 768 to get 146.
Bring next digit (0) of the dividend behind the 146 and repeat the process: 1460 / 311

Step 8:
If we divide 1460 by 311, we get 4 and a remainder of 216.
Record the quotient 4 as the next digit in the result. 
Result so far: 260524.0
Subtracting 1244 from 1460 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 9:
When dividing 2160 by 311, we get 6 with a remainder of 294.
Record the quotient 6 as the next digit in the result. 
Result so far: 260524.6
If we take 1866 away from 2160, we end up with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Advancing to step 10:
The number 311 fits into 2940 9 times, leaving a remainder of 141.
The next digit of our result is 9. 
Result so far: 260524.69
Subtracting 2799 from 2940 leaves us with 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

On to step 11:
1410 divided by 311 is 4 with a remainder of 166.
Record the quotient 4 as the next digit in the result. 
Result so far: 260524.694
Subtract 1244 from 1410 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 12:
311 goes into 1660 5 times with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 260524.6945
Subtract 1555 from 1660 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Advancing to step 13:
311 goes into 1050 3 times with a remainder of 117.
Put 3 as the next digit of the answer. 
Result so far: 260524.69453
If we subtract 933 from 1050, we get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Let's proceed to step 14:
The number 311 fits into 1170 3 times, leaving a remainder of 237.
The next digit of our result is 3. 
Result so far: 260524.694533
Subtracting 933 from 1170 leaves us with 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

The final result is 260524.694533 with a remainder of 2.37e-05.
