We divide 87909 by 25
Our goal is to divide 87909 by 25.

Step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 25

Let's proceed to step 2:
When dividing 87 by 25, we get 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 75 from 87 and we're left with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 25

Going ahead to step 3:
If we divide 129 by 25, we get 5 and a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Deduct 125 from 129 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 25

Step 4:
40 divided by 25 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 351.0
Deduct 25 from 40 and we're left with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 25

Going ahead to step 5:
159 divided by 25 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 3516.0
Subtract 150 from 159 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 6:
90 divided by 25 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3516.3
Subtract 75 from 90 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.

Going ahead to step 7:
150 divided by 25 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 3516.36
Subtracting 150 from 150 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.

On to step 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3516.36
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.

Going ahead to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3516.36
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.

The final result is 3516.36 with a remainder of 0.0.
