123487 ÷ 25 
We want to divide 123487 by 25.

Moving on to step 1:
If we divide 1 by 25, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 25

Let's proceed to step 2:
If we divide 12 by 25, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 25

Let's proceed to step 3:
If we divide 123 by 25, we get 4 and a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 100 from 123 to get 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 25

Moving on to step 4:
25 goes into 234 9 times with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 49.0
Deduct 225 from 234 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 25

On to step 5:
If we divide 98 by 25, we get 3 and a remainder of 23.
The next digit of our result is 3. 
Result so far: 493.0
Deduct 75 from 98 and we're left with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 25

On to step 6:
When dividing 237 by 25, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 4939.0
If we take 225 away from 237, 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.

Moving on to step 7:
120 divided by 25 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4939.4
If we subtract 100 from 120, we get 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 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 4939.48
Subtracting 200 from 200 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 9:
25 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: 4939.48
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.

Moving on to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 4939.48
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.

After the division, we end up with 4939.48 and a remainder of 0.0.
