We look at the division of 178015 by 20 
We want to divide 178015 by 20.

Step 1:
The number 20 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
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 / 20

Advancing to step 2:
20 can be fit into 17 0 times, resulting in a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Fetch the next digit (8) from the dividend, attach it to 17 and continue: 178 / 20

Advancing to step 3:
The number 20 fits into 178 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 160 from 178, we get 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 20

Let's proceed to step 4:
If we divide 180 by 20, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 89.0
Deduct 180 from 180 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 20

Moving on to step 5:
20 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: 890.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 20

Going ahead to step 6:
The number 20 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 8900.0
Subtract 0 from 15 to 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.

Advancing to step 7:
20 can be fit into 150 7 times, resulting in a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 8900.7
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.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8900.75
Subtract 100 from 100 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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8900.75
Subtracting 0 from 0 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:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8900.75
Subtracting 0 from 0 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.

After the division, we end up with 8900.75 and a remainder of 0.0.
