311 divided by 91 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 273 from 311 and we're left with 38.
Bring next digit (8) of the dividend behind the 38 and repeat the process: 388 / 91

Moving on to step 4:
388 divided by 91 is 4 with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we take 364 away from 388, we end up with 24.
Append the next digit (4) from the dividend to 24 and continue with: 244 / 91

On to step 5:
If we divide 244 by 91, we get 2 and a remainder of 62.
Record the quotient 2 as the next digit in the result. 
Result so far: 342.0
The remainder is 62 after subtracting 182 from 244.
Fetch the next digit (2) from the dividend, attach it to 62 and continue: 622 / 91

Moving on to step 6:
The number 91 fits into 622 6 times, leaving a remainder of 76.
The next digit of our result is 6. 
Result so far: 3426.0
If we take 546 away from 622, we end up with 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 91

On to step 7:
When dividing 764 by 91, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 34268.0
If we subtract 728 from 764, we get 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 91

Moving on to step 8:
367 divided by 91 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 342684.0
The remainder is 3 after subtracting 364 from 367.
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 9:
91 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 342684.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
300 divided by 91 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 342684.03
Deduct 273 from 300 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
91 goes into 270 2 times with a remainder of 88.
Write down 2 as next digit of the result. 
Result so far: 342684.032
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.

Moving on to step 12:
If we divide 880 by 91, we get 9 and a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 342684.0329
If we subtract 819 from 880, we 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.

Going ahead to step 13:
610 divided by 91 is 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 342684.03296
Deduct 546 from 610 and we're left 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.

Step 14:
When dividing 640 by 91, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 342684.032967
If we take 637 away from 640, we end up with 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 15:
If we divide 30 by 91, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 342684.032967
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 16:
If we divide 300 by 91, we get 3 and a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 342684.03296703
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.

Our division results in 342684.03296703 with a remaining 2.7e-08.
