We divide 87399601 by 25
Let's see how many times 25 fits into 87399601.

Let's proceed to step 1:
If we divide 8 by 25, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 25

Step 2:
87 divided by 25 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 75 from 87 leaves us with 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 25

On to step 3:
123 divided by 25 is 4 with a remainder of 23.
Write down 4 as next digit of the result. 
Result so far: 34.0
The remainder is 23 after subtracting 100 from 123.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 25

On to step 4:
When dividing 239 by 25, we get 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 349.0
The remainder is 14 after subtracting 225 from 239.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 25

Step 5:
149 divided by 25 is 5 with a remainder of 24.
The next digit of our result is 5. 
Result so far: 3495.0
If we take 125 away from 149, we end up with 24.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 25

On to step 6:
25 can be fit into 246 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 34959.0
Subtracting 225 from 246 leaves us with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 25

Going ahead to step 7:
25 can be fit into 210 8 times, resulting in a remainder of 10.
The next digit of our result is 8. 
Result so far: 349598.0
If we take 200 away from 210, we end up with 10.
Take the next digit (1) from the dividend and append it to 10, then repeat: 101 / 25

Step 8:
101 divided by 25 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 3495984.0
Subtract 100 from 101 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
25 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3495984.0
If we subtract 0 from 10, we get 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 10:
If we divide 100 by 25, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 3495984.04
The remainder is 0 after subtracting 100 from 100.
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 11:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3495984.04
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.

Let's proceed to step 12:
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: 3495984.04
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.

The final result is 3495984.04 with a remainder of 0.0.
