We look at the division of 578628 by 48 
We want to figure out the number of times 578628 can be divided by 48.

Moving on to step 1:
5 divided by 48 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 48

Step 2:
The number 48 fits into 57 1 times, leaving a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 48 from 57, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 48

Advancing to step 3:
The number 48 fits into 98 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 2 after subtracting 96 from 98.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 48

On to step 4:
When dividing 26 by 48, we get 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we take 0 away from 26, we end up with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 48

On to step 5:
When dividing 262 by 48, we get 5 with a remainder of 22.
Put 5 as the next digit of the answer. 
Result so far: 1205.0
The remainder is 22 after subtracting 240 from 262.
Take the next digit (8) from the dividend and append it to 22, then repeat: 228 / 48

On to step 6:
If we divide 228 by 48, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 12054.0
Subtracting 192 from 228 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
If we divide 360 by 48, we get 7 and a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 12054.7
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
The number 48 fits into 240 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 12054.75
Subtract 240 from 240 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.

On to step 9:
If we divide 0 by 48, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12054.75
If we subtract 0 from 0, 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.

Step 10:
0 divided by 48 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12054.75
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 12054.75 and a remainder of 0.0.
