We look at the division of 309514 by 86 
We want to divide 309514 by 86.

Going ahead to step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 86

Going ahead to step 2:
When dividing 30 by 86, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 86

Moving on to step 3:
If we divide 309 by 86, we get 3 and a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 258 from 309 leaves us with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 86

On to step 4:
86 can be fit into 515 5 times, resulting in a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we take 430 away from 515, we end up with 85.
Include the next digit (1) from the dividend after 85, then repeat: 851 / 86

Step 5:
The number 86 fits into 851 9 times, leaving a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 359.0
Subtracting 774 from 851 leaves us with 77.
Take the next digit (4) from the dividend and append it to 77, then repeat: 774 / 86

On to step 6:
86 can be fit into 774 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 3599.0
Subtracting 774 from 774 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
0 divided by 86 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3599.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 86, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3599.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 3599.0, with a leftover of 0.0.
