998486 divided by 25 
We're looking to find how many times 25 goes into 998486.

Let's proceed to step 1:
When dividing 9 by 25, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 25

Step 2:
25 can be fit into 99 3 times, resulting in a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 24 after subtracting 75 from 99.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 25

Moving on to step 3:
When dividing 248 by 25, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 39.0
Deduct 225 from 248 and we're left with 23.
Include the next digit (4) from the dividend after 23, then repeat: 234 / 25

Moving on to step 4:
25 can be fit into 234 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 399.0
Subtract 225 from 234 to get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 25

Moving on to step 5:
When dividing 98 by 25, we get 3 with a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 3993.0
Subtracting 75 from 98 leaves us with 23.
Grab the next digit (6) from the dividend, add it to 23, then carry on: 236 / 25

Step 6:
The number 25 fits into 236 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 39939.0
If we subtract 225 from 236, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 25, we get 4 and a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 39939.4
Deduct 100 from 110 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 25 fits into 100 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 39939.44
Subtract 100 from 100 to 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 39939.44 and a remainder of 0.0.
