We look at the division of 25490 by 48 
We want to figure out the number of times 25490 can be divided by 48.

Let's proceed to step 1:
The number 48 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 48

Going ahead to step 2:
The number 48 fits into 25 0 times, leaving a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 48

On to step 3:
48 goes into 254 5 times with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 240 from 254 leaves us with 14.
Append the next digit (9) from the dividend to 14 and continue with: 149 / 48

Step 4:
48 can be fit into 149 3 times, resulting in a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 53.0
Deduct 144 from 149 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 48

Let's proceed to step 5:
48 can be fit into 50 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 531.0
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 6:
The number 48 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 531.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 7:
If we divide 200 by 48, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 531.04
Subtract 192 from 200 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
48 can be fit into 80 1 times, resulting in a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 531.041
If we subtract 48 from 80, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
When dividing 320 by 48, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 531.0416
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
When dividing 320 by 48, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 531.04166
If we subtract 288 from 320, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 531.04166 and a remainder of 3.2e-05.
