We're dividing 173136 by 8 
Let's see how many times 8 fits into 173136.

Going ahead to step 1:
8 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 8

Advancing to step 2:
When dividing 17 by 8, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 16 away from 17, we end up with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 8

Moving on to step 3:
13 divided by 8 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 8 from 13 to get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 8

Moving on to step 4:
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: 216.0
Deduct 48 from 51 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 8

Moving on to step 5:
When dividing 33 by 8, we get 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 2164.0
Subtract 32 from 33 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 8

Advancing to step 6:
The number 8 fits into 16 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 21642.0
The remainder is 0 after subtracting 16 from 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21642.0
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.

Let's proceed to step 8:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21642.0
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.

The final result is 21642.0 with a remainder of 0.0.
