276555 divided by 86 
Our goal is to divide 276555 by 86.

Let's proceed to step 1:
If we divide 2 by 86, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 86

Step 2:
86 can be fit into 27 0 times, resulting in a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Include the next digit (6) from the dividend after 27, then repeat: 276 / 86

Advancing to step 3:
276 divided by 86 is 3 with a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 258 from 276, we get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 86

Let's proceed to step 4:
86 goes into 185 2 times with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
The remainder is 13 after subtracting 172 from 185.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 86

Let's proceed to step 5:
135 divided by 86 is 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 321.0
The remainder is 49 after subtracting 86 from 135.
Fetch the next digit (5) from the dividend, attach it to 49 and continue: 495 / 86

Advancing to step 6:
495 divided by 86 is 5 with a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 3215.0
Subtract 430 from 495 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 7:
The number 86 fits into 650 7 times, leaving a remainder of 48.
The next digit of our result is 7. 
Result so far: 3215.7
If we subtract 602 from 650, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 8:
When dividing 480 by 86, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 3215.75
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
86 goes into 500 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 3215.755
If we take 430 away from 500, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 3215.755 with a remainder of 0.007.
