We're dividing 178175 by 20 
We're looking to find how many times 20 goes into 178175.

Going ahead to step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 20

On to step 2:
The number 20 fits into 17 0 times, leaving a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 20

Advancing to step 3:
178 divided by 20 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 18 after subtracting 160 from 178.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 20

Step 4:
If we divide 181 by 20, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 89.0
The remainder is 1 after subtracting 180 from 181.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 20

Going ahead to step 5:
The number 20 fits into 17 0 times, leaving a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 890.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (5) from the dividend, add it to 17, then carry on: 175 / 20

Step 6:
175 divided by 20 is 8 with a remainder of 15.
Record the quotient 8 as the next digit in the result. 
Result so far: 8908.0
If we subtract 160 from 175, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
If we divide 150 by 20, we get 7 and a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 8908.7
Deduct 140 from 150 and we're left 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.

Step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8908.75
If we take 100 away from 100, 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.

Step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8908.75
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.

Advancing to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8908.75
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.

The final result is 8908.75 with a remainder of 0.0.
