We look at the division of 164215 by 8 
We're looking to find how many times 8 goes into 164215.

On to step 1:
8 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 8

Let's proceed to step 2:
If we divide 16 by 8, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 16 from 16 leaves us with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 8

On to step 3:
4 divided by 8 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 4 to get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 8

Let's proceed to step 4:
The number 8 fits into 42 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 205.0
If we take 40 away from 42, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 8

Going ahead to step 5:
When dividing 21 by 8, we get 2 with a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2052.0
Deduct 16 from 21 and we're left with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 8

Advancing to step 6:
If we divide 55 by 8, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 20526.0
Deduct 48 from 55 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
70 divided by 8 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 20526.8
If we subtract 64 from 70, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
When dividing 60 by 8, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 20526.87
Deduct 56 from 60 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.

Step 9:
8 goes into 40 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 20526.875
Subtracting 40 from 40 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.

Going ahead to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20526.875
Deduct 0 from 0 and we're left 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.

Step 11:
0 divided by 8 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20526.875
Deduct 0 from 0 and we're left 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 20526.875 and a remainder of 0.0.
