We divide 126239 by 25
We want to figure out the number of times 126239 can be divided by 25.

On to step 1:
The number 25 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 25

Moving on to step 2:
If we divide 12 by 25, we get 0 and a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 25

Advancing to step 3:
126 divided by 25 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 125 from 126 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 25

Advancing to step 4:
12 divided by 25 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtract 0 from 12 to get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 25

Let's proceed to step 5:
123 divided by 25 is 4 with a remainder of 23.
The next digit of our result is 4. 
Result so far: 504.0
Subtract 100 from 123 to get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 25

Advancing to step 6:
25 goes into 239 9 times with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 5049.0
Deduct 225 from 239 and we're left with 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:
25 goes into 140 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 5049.5
Subtracting 125 from 140 leaves us with 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:
If we divide 150 by 25, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 5049.56
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.

Let's proceed to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5049.56
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.

On to step 10:
25 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5049.56
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.

In conclusion, the division gives 5049.56 with a balance of 0.0.
