We're dividing 25508657 by 123 
Let's see how many times 123 fits into 25508657.

On to step 1:
123 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 123

Advancing to step 2:
123 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 123

On to step 3:
255 divided by 123 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 246 from 255 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 123

Going ahead to step 4:
123 goes into 90 0 times with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 90 after subtracting 0 from 90.
Grab the next digit (8) from the dividend, add it to 90, then carry on: 908 / 123

Moving on to step 5:
908 divided by 123 is 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 207.0
If we take 861 away from 908, we end up with 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 123

Step 6:
If we divide 476 by 123, we get 3 and a remainder of 107.
The next digit of our result is 3. 
Result so far: 2073.0
If we take 369 away from 476, we end up with 107.
Bring next digit (5) of the dividend behind the 107 and repeat the process: 1075 / 123

Step 7:
The number 123 fits into 1075 8 times, leaving a remainder of 91.
The number 8 becomes the next digit in our result. 
Result so far: 20738.0
The remainder is 91 after subtracting 984 from 1075.
Include the next digit (7) from the dividend after 91, then repeat: 917 / 123

Moving on to step 8:
123 goes into 917 7 times with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 207387.0
If we subtract 861 from 917, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 9:
123 goes into 560 4 times with a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 207387.4
If we subtract 492 from 560, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
680 divided by 123 is 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 207387.45
If we subtract 615 from 680, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 11:
If we divide 650 by 123, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 207387.455
Subtracting 615 from 650 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 207387.455 with a remaining 0.0035.
