We divide 25078173 by 45
Let's see how many times 45 fits into 25078173.

Moving on to step 1:
If we divide 2 by 45, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 45

On to step 2:
The number 45 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 45

Going ahead to step 3:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 225 from 250, we get 25.
Include the next digit (7) from the dividend after 25, then repeat: 257 / 45

Moving on to step 4:
The number 45 fits into 257 5 times, leaving a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtracting 225 from 257 leaves us with 32.
Append the next digit (8) from the dividend to 32 and continue with: 328 / 45

Advancing to step 5:
45 can be fit into 328 7 times, resulting in a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 557.0
Deduct 315 from 328 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 45

Moving on to step 6:
If we divide 131 by 45, we get 2 and a remainder of 41.
The number 2 becomes the next digit in our result. 
Result so far: 5572.0
If we subtract 90 from 131, we get 41.
Append the next digit (7) from the dividend to 41 and continue with: 417 / 45

Moving on to step 7:
When dividing 417 by 45, we get 9 with a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 55729.0
The remainder is 12 after subtracting 405 from 417.
Take the next digit (3) from the dividend and append it to 12, then repeat: 123 / 45

Going ahead to step 8:
If we divide 123 by 45, we get 2 and a remainder of 33.
The next digit of our result is 2. 
Result so far: 557292.0
If we subtract 90 from 123, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 9:
330 divided by 45 is 7 with a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 557292.7
The remainder is 15 after subtracting 315 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
150 divided by 45 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 557292.73
Subtracting 135 from 150 leaves us 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.

Step 11:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 557292.733
Deduct 135 from 150 and we're left 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.

Our division results in 557292.733 with a remaining 0.0015.
