We look at the division of 299808 by 86 
Our goal is to divide 299808 by 86.

Step 1:
When dividing 2 by 86, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 86

Let's proceed to step 2:
29 divided by 86 is 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 29, we get 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 86

Advancing to step 3:
The number 86 fits into 299 3 times, leaving a remainder of 41.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 258 from 299 to get 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 86

Moving on to step 4:
When dividing 418 by 86, we get 4 with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we take 344 away from 418, we end up with 74.
Append the next digit (0) from the dividend to 74 and continue with: 740 / 86

On to step 5:
The number 86 fits into 740 8 times, leaving a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 348.0
Deduct 688 from 740 and we're left with 52.
Take the next digit (8) from the dividend and append it to 52, then repeat: 528 / 86

On to step 6:
If we divide 528 by 86, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 3486.0
Subtract 516 from 528 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 86, we get 1 with a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 3486.1
Subtract 86 from 120 to 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.

Let's proceed to step 8:
The number 86 fits into 340 3 times, leaving a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 3486.13
If we take 258 away from 340, we end up 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.

On to step 9:
86 goes into 820 9 times with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 3486.139
Deduct 774 from 820 and we're left 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 10:
When dividing 460 by 86, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 3486.1395
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
When dividing 300 by 86, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 3486.13953
If we take 258 away from 300, we end up 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.

On to step 12:
420 divided by 86 is 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 3486.139534
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
86 goes into 760 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 3486.1395348
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 14:
If we divide 720 by 86, we get 8 and a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 3486.13953488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 3486.13953488 with a remainder of 3.2e-08.
