We divide 249307 by 45
We want to figure out the number of times 249307 can be divided by 45.

On to step 1:
The number 45 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 45

Let's proceed to step 2:
45 goes into 24 0 times with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 45

On to step 3:
45 goes into 249 5 times with a remainder of 24.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 24 after subtracting 225 from 249.
Include the next digit (3) from the dividend after 24, then repeat: 243 / 45

Step 4:
The number 45 fits into 243 5 times, leaving a remainder of 18.
The next digit of our result is 5. 
Result so far: 55.0
The remainder is 18 after subtracting 225 from 243.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 45

Let's proceed to step 5:
If we divide 180 by 45, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 554.0
Subtracting 180 from 180 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 45

On to step 6:
If we divide 7 by 45, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 5540.0
If we subtract 0 from 7, we 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.

Moving on to step 7:
45 goes into 70 1 times with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 5540.1
Subtract 45 from 70 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 5540.15
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 5540.155
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 5540.155 and a remainder of 0.0025.
