We're dividing 903249 by 10 
Let's see how many times 10 fits into 903249.

Advancing to step 1:
10 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 10

Step 2:
When dividing 90 by 10, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 90 away from 90, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 10

Moving on to step 3:
If we divide 3 by 10, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 90.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 10

On to step 4:
32 divided by 10 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 903.0
If we take 30 away from 32, we end up with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 10

Let's proceed to step 5:
If we divide 24 by 10, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 9032.0
Subtract 20 from 24 to get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 10

On to step 6:
10 goes into 49 4 times with a remainder of 9.
Write down 4 as next digit of the result. 
Result so far: 90324.0
If we subtract 40 from 49, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
10 goes into 90 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 90324.9
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
10 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 90324.9
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.

Step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 90324.9
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 90324.9 with a remainder of 0.0.
