Let's divide 45345 by 9
Let's see how many times 9 fits into 45345.

Step 1:
When dividing 4 by 9, we get 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

Moving on to step 2:
The number 9 fits into 45 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 45 from 45, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 9

Let's proceed to step 3:
When dividing 3 by 9, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 9

Step 4:
9 goes into 34 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 503.0
Subtracting 27 from 34 leaves us with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 9

Advancing to step 5:
If we divide 75 by 9, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 5038.0
If we subtract 72 from 75, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 6:
9 can be fit into 30 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 5038.3
Subtracting 27 from 30 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 9 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 5038.33
If we subtract 27 from 30, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 5038.33 with a remainder of 0.003.
