491489 ÷ 25 
We want to divide 491489 by 25.

Going ahead to step 1:
If we divide 4 by 25, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 25

Advancing to step 2:
25 goes into 49 1 times with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 25 from 49 and we're left with 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 25

Moving on to step 3:
25 can be fit into 241 9 times, resulting in a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtracting 225 from 241 leaves us with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 25

Moving on to step 4:
The number 25 fits into 164 6 times, leaving a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 196.0
If we subtract 150 from 164, we get 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 25

Advancing to step 5:
25 can be fit into 148 5 times, resulting in a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 1965.0
Deduct 125 from 148 and we're left with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 25

Step 6:
25 goes into 239 9 times with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 19659.0
If we take 225 away from 239, we end up 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.

Let's proceed to step 7:
140 divided by 25 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 19659.5
If we take 125 away from 140, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
When dividing 150 by 25, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 19659.56
If we take 150 away from 150, 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.

On to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19659.56
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.

On to step 10:
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: 19659.56
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.

The quotient of the division is 19659.56, and the remainder is 0.0.
