173155 ÷ 8 
Let's see how many times 8 fits into 173155.

Going ahead to step 1:
1 divided by 8 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 8

Going ahead to step 2:
8 can be fit into 17 2 times, resulting in a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 16 from 17 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 8

On to step 3:
When dividing 13 by 8, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 21.0
The remainder is 5 after subtracting 8 from 13.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 8

Advancing to step 4:
If we divide 51 by 8, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 216.0
If we take 48 away from 51, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 8

Let's proceed to step 5:
If we divide 35 by 8, we get 4 and a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 2164.0
Subtracting 32 from 35 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 8

On to step 6:
35 divided by 8 is 4 with a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 21644.0
If we take 32 away from 35, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
8 can be fit into 30 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 21644.3
Deduct 24 from 30 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
When dividing 60 by 8, we get 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 21644.37
The remainder is 4 after subtracting 56 from 60.
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:
40 divided by 8 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 21644.375
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.

Moving on to step 10:
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: 21644.375
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.

On to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 21644.375
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.

After the division, we end up with 21644.375 and a remainder of 0.0.
