We look at the division of 169551 by 8 
We want to divide 169551 by 8.

Moving on to step 1:
If we divide 1 by 8, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 8

Advancing to step 2:
16 divided by 8 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 16 away from 16, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 8

Step 3:
8 can be fit into 9 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 8 from 9 to get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 8

Going ahead to step 4:
If we divide 15 by 8, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 211.0
If we take 8 away from 15, we end up with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 8

On to step 5:
8 goes into 75 9 times with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 2119.0
If we take 72 away from 75, we end up with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 8

On to step 6:
31 divided by 8 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 21193.0
Subtract 24 from 31 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
8 can be fit into 70 8 times, resulting in a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 21193.8
Deduct 64 from 70 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.

Advancing to step 8:
8 goes into 60 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 21193.87
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.

Let's proceed to step 9:
8 goes into 40 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 21193.875
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.

Step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 21193.875
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.

Going ahead to step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 21193.875
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 result is 21193.875 with a remainder of 0.0.
