We're dividing 255135 by 86 
We want to figure out the number of times 255135 can be divided by 86.

Moving on to step 1:
The number 86 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 86

On to step 2:
If we divide 25 by 86, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 86

Let's proceed to step 3:
If we divide 255 by 86, we get 2 and a remainder of 83.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 83 after subtracting 172 from 255.
Fetch the next digit (1) from the dividend, attach it to 83 and continue: 831 / 86

Going ahead to step 4:
If we divide 831 by 86, we get 9 and a remainder of 57.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 774 away from 831, we end up with 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 86

Going ahead to step 5:
If we divide 573 by 86, we get 6 and a remainder of 57.
The number 6 becomes the next digit in our result. 
Result so far: 296.0
If we subtract 516 from 573, we get 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 86

Moving on to step 6:
86 goes into 575 6 times with a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 2966.0
Subtract 516 from 575 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
86 goes into 590 6 times with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 2966.6
Subtracting 516 from 590 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 8:
The number 86 fits into 740 8 times, leaving a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 2966.68
If we subtract 688 from 740, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 9:
520 divided by 86 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 2966.686
Subtracting 516 from 520 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
If we divide 40 by 86, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2966.686
Subtracting 0 from 40 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.

Advancing to step 11:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 2966.68604
If we take 344 away from 400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
86 goes into 560 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 2966.686046
Deduct 516 from 560 and we're left 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.

Let's proceed to step 13:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 2966.6860465
Deduct 430 from 440 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
When dividing 100 by 86, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 2966.68604651
If we take 86 away from 100, we end up 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.

The final outcome is 2966.68604651, with a leftover of 1.4e-08.
