258638 divided by 25 
We want to figure out the number of times 258638 can be divided by 25.

On to step 1:
When dividing 2 by 25, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 25

Advancing to step 2:
25 goes into 25 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 25 from 25, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 25

Let's proceed to step 3:
If we divide 8 by 25, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 25

Let's proceed to step 4:
The number 25 fits into 86 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 103.0
If we subtract 75 from 86, we get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 25

Going ahead to step 5:
When dividing 113 by 25, we get 4 with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 1034.0
If we take 100 away from 113, we end up with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 25

Let's proceed to step 6:
25 can be fit into 138 5 times, resulting in a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 10345.0
Subtracting 125 from 138 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
25 can be fit into 130 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 10345.5
Subtract 125 from 130 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
50 divided by 25 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 10345.52
If we take 50 away from 50, 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.

Let's proceed to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10345.52
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.

Going ahead to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 10345.52
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 outcome is 10345.52, with a leftover of 0.0.
