Let's divide 311308 by 91
We want to divide 311308 by 91.

Step 1:
3 divided by 91 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 91

Step 2:
If we divide 31 by 91, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 91

Advancing to step 3:
91 goes into 311 3 times with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 38 after subtracting 273 from 311.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 91

Going ahead to step 4:
If we divide 383 by 91, we get 4 and a remainder of 19.
The next digit of our result is 4. 
Result so far: 34.0
Subtracting 364 from 383 leaves us with 19.
Include the next digit (0) from the dividend after 19, then repeat: 190 / 91

Let's proceed to step 5:
91 can be fit into 190 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 342.0
Subtract 182 from 190 to get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 91

Advancing to step 6:
The number 91 fits into 88 0 times, leaving a remainder of 88.
Use 0 as the next digit of our solution. 
Result so far: 3420.0
Deduct 0 from 88 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 7:
When dividing 880 by 91, we get 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 3420.9
Subtract 819 from 880 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 8:
91 goes into 610 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 3420.96
Subtracting 546 from 610 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
91 can be fit into 640 7 times, resulting in a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 3420.967
If we subtract 637 from 640, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 10:
The number 91 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 3420.967
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 11:
91 can be fit into 300 3 times, resulting in a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 3420.96703
Subtract 273 from 300 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 12:
When dividing 270 by 91, we get 2 with a remainder of 88.
Use 2 as the next digit of our solution. 
Result so far: 3420.967032
Subtract 182 from 270 to get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 13:
91 can be fit into 880 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 3420.9670329
The remainder is 61 after subtracting 819 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 14:
If we divide 610 by 91, we get 6 and a remainder of 64.
The next digit of our result is 6. 
Result so far: 3420.96703296
If we subtract 546 from 610, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The quotient of the division is 3420.96703296, and the remainder is 6.4e-08.
