Let's divide 458989 by 25
Our goal is to divide 458989 by 25.

Going ahead to step 1:
The number 25 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 25

Let's proceed to step 2:
The number 25 fits into 45 1 times, leaving a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 25 from 45, we get 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 25

On to step 3:
208 divided by 25 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 200 from 208 and we're left with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 25

Going ahead to step 4:
When dividing 89 by 25, we get 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 183.0
The remainder is 14 after subtracting 75 from 89.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 25

On to step 5:
If we divide 148 by 25, we get 5 and a remainder of 23.
The next digit of our result is 5. 
Result so far: 1835.0
If we subtract 125 from 148, we get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 25

Step 6:
239 divided by 25 is 9 with a remainder of 14.
The next digit of our result is 9. 
Result so far: 18359.0
Deduct 225 from 239 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
140 divided by 25 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 18359.5
Subtract 125 from 140 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
The number 25 fits into 150 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 18359.56
If we subtract 150 from 150, 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.

Moving on to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18359.56
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:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18359.56
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.

Our division results in 18359.56 with a remaining 0.0.
