266690 ÷ 86 
We want to figure out the number of times 266690 can be divided by 86.

Step 1:
When dividing 2 by 86, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 86

Moving on to step 2:
86 can be fit into 26 0 times, resulting in a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Include the next digit (6) from the dividend after 26, then repeat: 266 / 86

On to step 3:
When dividing 266 by 86, we get 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 258 from 266 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 86

Advancing to step 4:
86 goes into 86 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtracting 86 from 86 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 86

Step 5:
If we divide 9 by 86, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 310.0
If we subtract 0 from 9, we get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 86

Moving on to step 6:
90 divided by 86 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 3101.0
Subtracting 86 from 90 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3101.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
86 can be fit into 400 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 3101.04
Deduct 344 from 400 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
560 divided by 86 is 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 3101.046
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
86 goes into 440 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 3101.0465
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
The number 86 fits into 100 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 3101.04651
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.

Advancing to step 12:
140 divided by 86 is 1 with a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 3101.046511
Subtracting 86 from 140 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The quotient of the division is 3101.046511, and the remainder is 5.4e-06.
