We look at the division of 490878 by 48 
We want to figure out the number of times 490878 can be divided by 48.

On to step 1:
When dividing 4 by 48, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 48

Advancing to step 2:
The number 48 fits into 49 1 times, leaving a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 48 away from 49, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 48

Moving on to step 3:
If we divide 10 by 48, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 10 to get 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 48

Step 4:
If we divide 108 by 48, we get 2 and a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we subtract 96 from 108, we get 12.
Append the next digit (7) from the dividend to 12 and continue with: 127 / 48

On to step 5:
If we divide 127 by 48, we get 2 and a remainder of 31.
The next digit of our result is 2. 
Result so far: 1022.0
Deduct 96 from 127 and we're left with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 48

Moving on to step 6:
If we divide 318 by 48, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 10226.0
Subtract 288 from 318 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 7:
48 goes into 300 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 10226.6
If we take 288 away from 300, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
The number 48 fits into 120 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 10226.62
If we take 96 away from 120, we end up 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.

On to step 9:
If we divide 240 by 48, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10226.625
Subtracting 240 from 240 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.

Going ahead to step 10:
48 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10226.625
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 11:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10226.625
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 10226.625 and a remainder of 0.0.
