211866 ÷ 8 
We want to divide 211866 by 8.

Step 1:
8 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 8

Moving on to step 2:
When dividing 21 by 8, we get 2 with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 5 after subtracting 16 from 21.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 8

Step 3:
If we divide 51 by 8, we get 6 and a remainder of 3.
The next digit of our result is 6. 
Result so far: 26.0
Subtract 48 from 51 to get 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 8

Going ahead to step 4:
The number 8 fits into 38 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 264.0
If we subtract 32 from 38, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 8

Let's proceed to step 5:
66 divided by 8 is 8 with a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 2648.0
The remainder is 2 after subtracting 64 from 66.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 8

Going ahead to step 6:
26 divided by 8 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 26483.0
Subtracting 24 from 26 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 26483.2
Deduct 16 from 20 and we're left 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.

Advancing to step 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 26483.25
If we subtract 40 from 40, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26483.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26483.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 26483.25 and a remainder of 0.0.
