28451142 ÷ 25 
We want to divide 28451142 by 25.

Step 1:
2 divided by 25 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 25

Moving on to step 2:
28 divided by 25 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 25 from 28 to get 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 25

Moving on to step 3:
25 can be fit into 34 1 times, resulting in a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 25 from 34, we get 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 25

On to step 4:
25 can be fit into 95 3 times, resulting in a remainder of 20.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Subtracting 75 from 95 leaves us with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 25

Let's proceed to step 5:
201 divided by 25 is 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 1138.0
If we take 200 away from 201, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 25

On to step 6:
25 goes into 11 0 times with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 11380.0
If we subtract 0 from 11, we get 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 25

Moving on to step 7:
114 divided by 25 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 113804.0
Subtract 100 from 114 to get 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 25

On to step 8:
25 can be fit into 142 5 times, resulting in a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 1138045.0
The remainder is 17 after subtracting 125 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
25 goes into 170 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 1138045.6
Subtracting 150 from 170 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
200 divided by 25 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1138045.68
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 25 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1138045.68
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.

Moving on to step 12:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1138045.68
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.

The final outcome is 1138045.68, with a leftover of 0.0.
