We're dividing 266746 by 86 
Let's see how many times 86 fits into 266746.

On to step 1:
When dividing 2 by 86, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 86

On to step 2:
If we divide 26 by 86, we get 0 and a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 86

Going ahead to step 3:
86 can be fit into 266 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 258 from 266 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 86

Going ahead to step 4:
When dividing 87 by 86, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Deduct 86 from 87 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 86

On to step 5:
86 goes into 14 0 times with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 310.0
If we subtract 0 from 14, we get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 86

On to step 6:
146 divided by 86 is 1 with a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 3101.0
The remainder is 60 after subtracting 86 from 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 3101.6
If we subtract 516 from 600, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 8:
The number 86 fits into 840 9 times, leaving a remainder of 66.
The next digit of our result is 9. 
Result so far: 3101.69
If we take 774 away from 840, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Advancing to step 9:
The number 86 fits into 660 7 times, leaving a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 3101.697
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 10:
If we divide 580 by 86, we get 6 and a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 3101.6976
Deduct 516 from 580 and we're left with 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 11:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Use 7 as the next digit of our solution. 
Result so far: 3101.69767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
When dividing 380 by 86, we get 4 with a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 3101.697674
Subtracting 344 from 380 leaves us with 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 13:
360 divided by 86 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 3101.6976744
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 3101.6976744 with a remainder of 1.6e-07.
