300260 divided by 86 
Our goal is to divide 300260 by 86.

Going ahead to step 1:
3 divided by 86 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 86

Let's proceed to step 2:
The number 86 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 86

Let's proceed to step 3:
86 goes into 300 3 times with a remainder of 42.
The next digit of our result is 3. 
Result so far: 3.0
If we take 258 away from 300, we end up with 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 86

Step 4:
86 can be fit into 422 4 times, resulting in a remainder of 78.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we take 344 away from 422, we end up with 78.
Grab the next digit (6) from the dividend, add it to 78, then carry on: 786 / 86

Step 5:
786 divided by 86 is 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 349.0
Subtract 774 from 786 to get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 86

Step 6:
86 can be fit into 120 1 times, resulting in a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 3491.0
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
The number 86 fits into 340 3 times, leaving a remainder of 82.
The next digit of our result is 3. 
Result so far: 3491.3
Deduct 258 from 340 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 8:
If we divide 820 by 86, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 3491.39
If we take 774 away from 820, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
86 goes into 460 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 3491.395
The remainder is 30 after subtracting 430 from 460.
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:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 3491.3953
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
420 divided by 86 is 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 3491.39534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
If we divide 760 by 86, we get 8 and a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 3491.395348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
720 divided by 86 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 3491.3953488
The remainder is 32 after subtracting 688 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 3491.3953488 with a balance of 3.2e-07.
