25480017 ÷ 45 
We want to figure out the number of times 25480017 can be divided by 45.

Let's proceed to step 1:
2 divided by 45 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
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:
45 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 45

Going ahead to step 3:
When dividing 254 by 45, we get 5 with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 225 away from 254, we end up with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 45

Moving on to step 4:
When dividing 298 by 45, we get 6 with a remainder of 28.
The next digit of our result is 6. 
Result so far: 56.0
Deduct 270 from 298 and we're left with 28.
Fetch the next digit (0) from the dividend, attach it to 28 and continue: 280 / 45

Going ahead to step 5:
When dividing 280 by 45, we get 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 566.0
If we subtract 270 from 280, we get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 45

Step 6:
45 can be fit into 100 2 times, resulting in a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 5662.0
If we take 90 away from 100, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 45

Going ahead to step 7:
If we divide 101 by 45, we get 2 and a remainder of 11.
The next digit of our result is 2. 
Result so far: 56622.0
Deduct 90 from 101 and we're left with 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 45

Advancing to step 8:
45 can be fit into 117 2 times, resulting in a remainder of 27.
The next digit of our result is 2. 
Result so far: 566222.0
If we take 90 away from 117, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 9:
45 can be fit into 270 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 566222.6
Subtracting 270 from 270 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.

On to step 10:
45 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 566222.6
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
45 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 566222.6
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.

After the division, we end up with 566222.6 and a remainder of 0.0.
