We look at the division of 310328 by 86 
Let's see how many times 86 fits into 310328.

Going ahead to step 1:
If we divide 3 by 86, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 86

Step 2:
86 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 86

On to step 3:
86 goes into 310 3 times with a remainder of 52.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 258 from 310 and we're left with 52.
Bring next digit (3) of the dividend behind the 52 and repeat the process: 523 / 86

Going ahead to step 4:
523 divided by 86 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Subtracting 516 from 523 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 86

Step 5:
When dividing 72 by 86, we get 0 with a remainder of 72.
The next digit of our result is 0. 
Result so far: 360.0
Subtracting 0 from 72 leaves us with 72.
Take the next digit (8) from the dividend and append it to 72, then repeat: 728 / 86

Moving on to step 6:
When dividing 728 by 86, we get 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 3608.0
If we take 688 away from 728, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
If we divide 400 by 86, we get 4 and a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 3608.4
If we subtract 344 from 400, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 8:
86 goes into 560 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 3608.46
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
When dividing 440 by 86, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 3608.465
If we subtract 430 from 440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
86 goes into 100 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 3608.4651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
86 can be fit into 140 1 times, resulting in a remainder of 54.
Use 1 as the next digit of our solution. 
Result so far: 3608.46511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 3608.46511, with a leftover of 5.4e-05.
