396 divided by 311 is 1 with a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 311 from 396 and we're left with 85.
Fetch the next digit (9) from the dividend, attach it to 85 and continue: 859 / 311

Step 5:
311 goes into 859 2 times with a remainder of 237.
Write down 2 as next digit of the result. 
Result so far: 212.0
Subtracting 622 from 859 leaves us with 237.
Append the next digit (9) from the dividend to 237 and continue with: 2379 / 311

Moving on to step 6:
When dividing 2379 by 311, we get 7 with a remainder of 202.
Put 7 as the next digit of the answer. 
Result so far: 2127.0
Deduct 2177 from 2379 and we're left with 202.
Bring next digit (0) of the dividend behind the 202 and repeat the process: 2020 / 311

Let's proceed to step 7:
The number 311 fits into 2020 6 times, leaving a remainder of 154.
Record the quotient 6 as the next digit in the result. 
Result so far: 21276.0
If we take 1866 away from 2020, we end up with 154.
Fetch the next digit (9) from the dividend, attach it to 154 and continue: 1549 / 311

Moving on to step 8:
311 goes into 1549 4 times with a remainder of 305.
The next digit of our result is 4. 
Result so far: 212764.0
The remainder is 305 after subtracting 1244 from 1549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Advancing to step 9:
When dividing 3050 by 311, we get 9 with a remainder of 251.
The number 9 becomes the next digit in our result. 
Result so far: 212764.9
Subtracting 2799 from 3050 leaves us with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 10:
The number 311 fits into 2510 8 times, leaving a remainder of 22.
The next digit of our result is 8. 
Result so far: 212764.98
Subtracting 2488 from 2510 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
220 divided by 311 is 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 212764.98
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 12:
2200 divided by 311 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 212764.9807
If we take 2177 away from 2200, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 13:
If we divide 230 by 311, we get 0 and a remainder of 230.
Record the quotient 0 as the next digit in the result. 
Result so far: 212764.9807
The remainder is 230 after subtracting 0 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Moving on to step 14:
311 can be fit into 2300 7 times, resulting in a remainder of 123.
Use 7 as the next digit of our solution. 
Result so far: 212764.980707
Subtract 2177 from 2300 to get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 15:
311 goes into 1230 3 times with a remainder of 297.
Write down 3 as next digit of the result. 
Result so far: 212764.9807073
Subtract 933 from 1230 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 16:
The number 311 fits into 2970 9 times, leaving a remainder of 171.
Record the quotient 9 as the next digit in the result. 
Result so far: 212764.98070739
The remainder is 171 after subtracting 2799 from 2970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

In conclusion, the division gives 212764.98070739 with a balance of 1.71e-07.
