480978 ÷ 12 
We want to figure out the number of times 480978 can be divided by 12.

Advancing to step 1:
When dividing 4 by 12, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 12

Moving on to step 2:
48 divided by 12 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 0 after subtracting 48 from 48.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 12

Moving on to step 3:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 0 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 12

Step 4:
When dividing 9 by 12, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 400.0
If we take 0 away from 9, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 12

Going ahead to step 5:
The number 12 fits into 97 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 4008.0
Subtracting 96 from 97 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 12

Moving on to step 6:
When dividing 18 by 12, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 40081.0
Subtracting 12 from 18 leaves us 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.

Going ahead to step 7:
12 goes into 60 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 40081.5
If we subtract 60 from 60, 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.

On to step 8:
0 divided by 12 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40081.5
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.

On to step 9:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40081.5
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.

The quotient of the division is 40081.5, and the remainder is 0.0.
