We're dividing 126787 by 25 
We want to figure out the number of times 126787 can be divided by 25.

Advancing to step 1:
25 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 25

Going ahead to step 2:
When dividing 12 by 25, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 25

Let's proceed to step 3:
126 divided by 25 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 125 from 126 to get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 25

Advancing to step 4:
25 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 50.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 25

Moving on to step 5:
178 divided by 25 is 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 507.0
Deduct 175 from 178 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 25

Step 6:
If we divide 37 by 25, we get 1 and a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 5071.0
The remainder is 12 after subtracting 25 from 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
25 can be fit into 120 4 times, resulting in a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 5071.4
If we subtract 100 from 120, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
25 goes into 200 8 times with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 5071.48
If we take 200 away from 200, 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 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5071.48
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.

Step 10:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5071.48
Deduct 0 from 0 and we're left 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 5071.48 with a remainder of 0.0.
