259091 divided by 86 
Our goal is to divide 259091 by 86.

Advancing to step 1:
When dividing 2 by 86, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 86

Advancing to step 2:
25 divided by 86 is 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 86

Let's proceed to step 3:
86 goes into 259 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 258 from 259 and we're left with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 86

Moving on to step 4:
10 divided by 86 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 30.0
Deduct 0 from 10 and we're left with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 86

Moving on to step 5:
86 can be fit into 109 1 times, resulting in a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 301.0
Deduct 86 from 109 and we're left with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 86

Let's proceed to step 6:
The number 86 fits into 231 2 times, leaving a remainder of 59.
The next digit of our result is 2. 
Result so far: 3012.0
The remainder is 59 after subtracting 172 from 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
590 divided by 86 is 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 3012.6
Subtract 516 from 590 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 8:
When dividing 740 by 86, we get 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 3012.68
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.

Going ahead to step 9:
If we divide 520 by 86, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 3012.686
The remainder is 4 after subtracting 516 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3012.686
If we take 0 away from 40, we end up 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 11:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 3012.68604
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.

Going ahead to step 12:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 3012.686046
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.

Going ahead to step 13:
86 goes into 440 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3012.6860465
Subtracting 430 from 440 leaves us 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.

On to step 14:
86 goes into 100 1 times with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 3012.68604651
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 3012.68604651 with a remaining 1.4e-08.
