25 divided by 23 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 23 from 25 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 23

Moving on to step 3:
If we divide 22 by 23, we get 0 and a remainder of 22.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 22 after subtracting 0 from 22.
Include the next digit (4) from the dividend after 22, then repeat: 224 / 23

Advancing to step 4:
23 goes into 224 9 times with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 109.0
The remainder is 17 after subtracting 207 from 224.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 23

Advancing to step 5:
The number 23 fits into 178 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 1097.0
Deduct 161 from 178 and we're left with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 23

Going ahead to step 6:
The number 23 fits into 171 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 10977.0
Subtract 161 from 171 to get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 23

Advancing to step 7:
23 goes into 105 4 times with a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 109774.0
The remainder is 13 after subtracting 92 from 105.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 23

Going ahead to step 8:
130 divided by 23 is 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1097745.0
The remainder is 15 after subtracting 115 from 130.
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 9:
150 divided by 23 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 1097745.6
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 10:
23 goes into 120 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1097745.65
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 11:
23 goes into 50 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 1097745.652
Deduct 46 from 50 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
When dividing 40 by 23, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1097745.6521
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
23 goes into 170 7 times with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 1097745.65217
Subtracting 161 from 170 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 14:
When dividing 90 by 23, we get 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 1097745.652173
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 15:
23 goes into 210 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1097745.6521739
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 16:
30 divided by 23 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1097745.65217391
If we subtract 23 from 30, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 1097745.65217391, with a leftover of 7e-09.
