Let's divide 215090 by 8
Let's see how many times 8 fits into 215090.

Going ahead to step 1:
The number 8 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 8

On to step 2:
The number 8 fits into 21 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 16 away from 21, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 8

Step 3:
8 can be fit into 55 6 times, resulting in a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 48 away from 55, we end up with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 8

Moving on to step 4:
70 divided by 8 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 268.0
If we subtract 64 from 70, we get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 8

Advancing to step 5:
If we divide 69 by 8, we get 8 and a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 2688.0
If we subtract 64 from 69, we get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 8

Going ahead to step 6:
50 divided by 8 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 26886.0
If we subtract 48 from 50, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 8, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 26886.2
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.

Moving on to step 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 26886.25
The remainder is 0 after subtracting 40 from 40.
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:
If we divide 0 by 8, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 26886.25
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.

Let's proceed to step 10:
0 divided by 8 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 26886.25
If we subtract 0 from 0, 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.

The final outcome is 26886.25, with a leftover of 0.0.
