We're dividing 256149 by 86 
We're looking to find how many times 86 goes into 256149.

Advancing to step 1:
If we divide 2 by 86, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 86

Let's proceed to step 2:
25 divided by 86 is 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 86

Step 3:
When dividing 256 by 86, we get 2 with a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 172 from 256 to get 84.
Take the next digit (1) from the dividend and append it to 84, then repeat: 841 / 86

Going ahead to step 4:
86 can be fit into 841 9 times, resulting in a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 774 from 841 leaves us with 67.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 86

Step 5:
86 goes into 674 7 times with a remainder of 72.
The next digit of our result is 7. 
Result so far: 297.0
The remainder is 72 after subtracting 602 from 674.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 86

Let's proceed to step 6:
86 can be fit into 729 8 times, resulting in a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 2978.0
Deduct 688 from 729 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
410 divided by 86 is 4 with a remainder of 66.
The next digit of our result is 4. 
Result so far: 2978.4
The remainder is 66 after subtracting 344 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 8:
If we divide 660 by 86, we get 7 and a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 2978.47
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 9:
86 goes into 580 6 times with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 2978.476
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 10:
86 goes into 640 7 times with a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 2978.4767
Subtract 602 from 640 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 11:
When dividing 380 by 86, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 2978.47674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
86 goes into 360 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 2978.476744
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 2978.476744 with a balance of 1.6e-06.
