We look at the division of 20478 by 10 
Our goal is to divide 20478 by 10.

Moving on to step 1:
When dividing 2 by 10, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 10

Step 2:
20 divided by 10 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 20 from 20, we get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 10

Moving on to step 3:
The number 10 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we subtract 0 from 4, we get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 10

Advancing to step 4:
The number 10 fits into 47 4 times, leaving a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 204.0
The remainder is 7 after subtracting 40 from 47.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 10

Going ahead to step 5:
78 divided by 10 is 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 2047.0
If we take 70 away from 78, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 6:
10 can be fit into 80 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 2047.8
Deduct 80 from 80 and we're left 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.

Let's proceed to step 7:
10 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: 2047.8
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.

Advancing to step 8:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2047.8
Deduct 0 from 0 and we're left 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.

Our division results in 2047.8 with a remaining 0.0.
