We look at the division of 86629 by 8 
Let's see how many times 8 fits into 86629.

Going ahead to step 1:
8 goes into 8 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 8

Going ahead to step 2:
When dividing 6 by 8, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 8

Moving on to step 3:
8 can be fit into 66 8 times, resulting in a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 108.0
The remainder is 2 after subtracting 64 from 66.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 8

On to step 4:
22 divided by 8 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 1082.0
Deduct 16 from 22 and we're left with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 8

Advancing to step 5:
8 goes into 69 8 times with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 10828.0
Subtracting 64 from 69 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 6:
8 can be fit into 50 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 10828.6
If we take 48 away from 50, we end up 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.

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: 10828.62
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.

Let's proceed 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: 10828.625
If we take 40 away from 40, we end up 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.

Advancing to step 9:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10828.625
If we take 0 away from 0, we end up 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:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10828.625
Subtract 0 from 0 to 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.

After the division, we end up with 10828.625 and a remainder of 0.0.
