We're dividing 990537 by 25 
Our goal is to divide 990537 by 25.

On to step 1:
25 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 25

On to step 2:
99 divided by 25 is 3 with a remainder of 24.
The next digit of our result is 3. 
Result so far: 3.0
If we take 75 away from 99, we end up with 24.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 25

Let's proceed to step 3:
25 goes into 240 9 times with a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 225 away from 240, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 25

Moving on to step 4:
155 divided by 25 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 396.0
Subtracting 150 from 155 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 25

Advancing to step 5:
When dividing 53 by 25, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 3962.0
If we subtract 50 from 53, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 25

On to step 6:
If we divide 37 by 25, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 39621.0
If we take 25 away from 37, 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:
If we divide 120 by 25, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 39621.4
Deduct 100 from 120 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 39621.48
Deduct 200 from 200 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 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39621.48
Subtract 0 from 0 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.

Advancing to step 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 39621.48
Subtracting 0 from 0 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.

The final result is 39621.48 with a remainder of 0.0.
