We divide 450254 by 5
Let's see how many times 5 fits into 450254.

Step 1:
4 divided by 5 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 5

Moving on to step 2:
45 divided by 5 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 45 away from 45, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 5

Let's proceed to step 3:
5 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 5

Let's proceed to step 4:
5 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 900.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 5

Let's proceed to step 5:
When dividing 25 by 5, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 9005.0
If we subtract 25 from 25, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 5

Moving on to step 6:
The number 5 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 90050.0
Subtract 0 from 4 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
The number 5 fits into 40 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 90050.8
If we subtract 40 from 40, 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.

Going ahead to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 90050.8
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.

Going ahead to step 9:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 90050.8
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 result is 90050.8 with a remainder of 0.0.
