We're dividing 266387 by 86 
We want to figure out the number of times 266387 can be divided by 86.

Going ahead to step 1:
86 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 86

Going ahead to step 2:
86 goes into 26 0 times with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 86

Moving on to step 3:
If we divide 266 by 86, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 258 from 266 and we're left with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 86

Step 4:
86 can be fit into 83 0 times, resulting in a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 30.0
If we subtract 0 from 83, we get 83.
Fetch the next digit (8) from the dividend, attach it to 83 and continue: 838 / 86

Going ahead to step 5:
When dividing 838 by 86, we get 9 with a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 309.0
Subtract 774 from 838 to get 64.
Take the next digit (7) from the dividend and append it to 64, then repeat: 647 / 86

Going ahead to step 6:
86 goes into 647 7 times with a remainder of 45.
The number 7 becomes the next digit in our result. 
Result so far: 3097.0
Subtracting 602 from 647 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
When dividing 450 by 86, we get 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 3097.5
Subtract 430 from 450 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
200 divided by 86 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 3097.52
If we take 172 away from 200, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 3097.523
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 10:
The number 86 fits into 220 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 3097.5232
Subtracting 172 from 220 leaves us with 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 11:
If we divide 480 by 86, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 3097.52325
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.

Advancing to step 12:
500 divided by 86 is 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 3097.523255
Subtracting 430 from 500 leaves us 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 3097.523255 with a remainder of 7e-06.
