We look at the division of 302330 by 86 
Let's see how many times 86 fits into 302330.

Advancing to step 1:
86 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 86

Going ahead to step 2:
30 divided by 86 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 86

Let's proceed to step 3:
302 divided by 86 is 3 with a remainder of 44.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 258 from 302 and we're left with 44.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 86

Let's proceed to step 4:
443 divided by 86 is 5 with a remainder of 13.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 430 from 443 to get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 86

Step 5:
86 can be fit into 133 1 times, resulting in a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 351.0
Subtract 86 from 133 to get 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 86

On to step 6:
If we divide 470 by 86, we get 5 and a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 3515.0
Subtracting 430 from 470 leaves us 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:
86 can be fit into 400 4 times, resulting in a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 3515.4
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
560 divided by 86 is 6 with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 3515.46
If we take 516 away from 560, we end up 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.

Step 9:
The number 86 fits into 440 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 3515.465
Subtract 430 from 440 to 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.

Going ahead to step 10:
If we divide 100 by 86, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 3515.4651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
86 goes into 140 1 times with a remainder of 54.
The next digit of our result is 1. 
Result so far: 3515.46511
If we take 86 away from 140, we end up 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.

In conclusion, the division gives 3515.46511 with a balance of 5.4e-05.
