Let's divide 218639 by 25
Let's see how many times 25 fits into 218639.

On to step 1:
If we divide 2 by 25, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 25

Let's proceed to step 2:
If we divide 21 by 25, we get 0 and a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 25

Advancing to step 3:
218 divided by 25 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 200 from 218, we get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 25

Moving on to step 4:
If we divide 186 by 25, we get 7 and a remainder of 11.
The next digit of our result is 7. 
Result so far: 87.0
Subtracting 175 from 186 leaves us with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 25

Moving on to step 5:
If we divide 113 by 25, we get 4 and a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 874.0
The remainder is 13 after subtracting 100 from 113.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 25

Step 6:
25 can be fit into 139 5 times, resulting in a remainder of 14.
The next digit of our result is 5. 
Result so far: 8745.0
Subtract 125 from 139 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
The number 25 fits into 140 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8745.5
If we subtract 125 from 140, we 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.

Let's proceed to step 8:
25 goes into 150 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 8745.56
If we subtract 150 from 150, we 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.

On to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8745.56
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 10:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8745.56
If we take 0 away from 0, we end up 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 8745.56 with a remainder of 0.0.
