We're dividing 176391 by 20 
We're looking to find how many times 20 goes into 176391.

Moving on to step 1:
20 goes into 1 0 times with 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.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 20

Advancing to step 2:
The number 20 fits into 17 0 times, leaving a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 20

On to step 3:
If we divide 176 by 20, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 160 away from 176, we end up with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 20

Let's proceed to step 4:
20 can be fit into 163 8 times, resulting in a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 88.0
Subtract 160 from 163 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 20

Advancing to step 5:
The number 20 fits into 39 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 881.0
Subtract 20 from 39 to get 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 20

On to step 6:
20 can be fit into 191 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 8819.0
If we take 180 away from 191, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
20 goes into 110 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 8819.5
Subtracting 100 from 110 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8819.55
If we subtract 100 from 100, 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 8819.55 with a remainder of 0.0.
