We look at the division of 452609 by 9 
Let's see how many times 9 fits into 452609.

Going ahead to step 1:
4 divided by 9 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 9

On to step 2:
9 can be fit into 45 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we take 45 away from 45, we end up with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 9

On to step 3:
2 divided by 9 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 50.0
Subtract 0 from 2 to get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 9

Advancing to step 4:
The number 9 fits into 26 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 502.0
Subtracting 18 from 26 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 9

On to step 5:
The number 9 fits into 80 8 times, leaving a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 5028.0
Subtract 72 from 80 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 9

Moving on to step 6:
When dividing 89 by 9, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 50289.0
Subtract 81 from 89 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
9 can be fit into 80 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 50289.8
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
9 can be fit into 80 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 50289.88
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 50289.88 with a remainder of 0.008.
