25457278 divided by 23 
We want to divide 25457278 by 23.

Step 1:
23 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 23

On to step 2:
When dividing 25 by 23, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 23 from 25 to get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 23

Step 3:
The number 23 fits into 24 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 23 from 24 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 23

Going ahead to step 4:
The number 23 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 110.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 23

Step 5:
23 can be fit into 157 6 times, resulting in a remainder of 19.
The next digit of our result is 6. 
Result so far: 1106.0
If we take 138 away from 157, we end up with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 23

Moving on to step 6:
The number 23 fits into 192 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 11068.0
If we take 184 away from 192, we end up with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 23

Let's proceed to step 7:
23 can be fit into 87 3 times, resulting in a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 110683.0
Subtracting 69 from 87 leaves us with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 23

Moving on to step 8:
23 goes into 188 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 1106838.0
Subtract 184 from 188 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 23 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1106838.1
If we take 23 away from 40, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
23 goes into 170 7 times with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 1106838.17
If we subtract 161 from 170, we get 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 11:
When dividing 90 by 23, we get 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 1106838.173
If we subtract 69 from 90, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
If we divide 210 by 23, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 1106838.1739
If we take 207 away from 210, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 13:
If we divide 30 by 23, we get 1 and a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1106838.17391
Subtract 23 from 30 to 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.

On to step 14:
If we divide 70 by 23, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 1106838.173913
If we take 69 away from 70, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 15:
10 divided by 23 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 1106838.173913
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 16:
23 goes into 100 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1106838.17391304
If we take 92 away from 100, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 1106838.17391304, with a leftover of 8e-09.
