We divide 998039 by 25
We want to figure out the number of times 998039 can be divided by 25.

Step 1:
If we divide 9 by 25, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 25

Advancing to step 2:
When dividing 99 by 25, we get 3 with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 75 from 99 and we're left with 24.
Grab the next digit (8) from the dividend, add it to 24, then carry on: 248 / 25

Advancing to step 3:
25 can be fit into 248 9 times, resulting in a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Deduct 225 from 248 and we're left with 23.
Take the next digit (0) from the dividend and append it to 23, then repeat: 230 / 25

Moving on to step 4:
If we divide 230 by 25, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 399.0
Subtracting 225 from 230 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 25

Let's proceed to step 5:
25 can be fit into 53 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 3992.0
If we subtract 50 from 53, we get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 25

On to step 6:
39 divided by 25 is 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 39921.0
If we take 25 away from 39, 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.

Advancing to step 7:
140 divided by 25 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 39921.5
The remainder is 15 after subtracting 125 from 140.
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.
Put 6 as the next digit of the answer. 
Result so far: 39921.56
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39921.56
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.

Step 10:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39921.56
The remainder is 0 after subtracting 0 from 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 39921.56 and a remainder of 0.0.
