We're dividing 25945251 by 45 
Let's see how many times 45 fits into 25945251.

Moving on to step 1:
If we divide 2 by 45, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 45

Let's proceed to step 2:
If we divide 25 by 45, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 45

Advancing to step 3:
259 divided by 45 is 5 with a remainder of 34.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 225 from 259 and we're left with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 45

Going ahead to step 4:
344 divided by 45 is 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 57.0
If we take 315 away from 344, we end up with 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 45

Let's proceed to step 5:
When dividing 295 by 45, we get 6 with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 576.0
The remainder is 25 after subtracting 270 from 295.
Bring next digit (2) of the dividend behind the 25 and repeat the process: 252 / 45

Advancing to step 6:
When dividing 252 by 45, we get 5 with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 5765.0
The remainder is 27 after subtracting 225 from 252.
Grab the next digit (5) from the dividend, add it to 27, then carry on: 275 / 45

Step 7:
If we divide 275 by 45, we get 6 and a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 57656.0
If we take 270 away from 275, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 45

Step 8:
The number 45 fits into 51 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 576561.0
If we take 45 away from 51, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
The number 45 fits into 60 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 576561.1
If we take 45 away from 60, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 10:
45 goes into 150 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 576561.13
If we subtract 135 from 150, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 11:
When dividing 150 by 45, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 576561.133
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 576561.133, with a leftover of 0.0015.
