903108 ÷ 2 
We want to divide 903108 by 2.

Step 1:
2 can be fit into 9 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 8 from 9 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Moving on to step 2:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 10 from 10 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

Let's proceed to step 3:
2 goes into 3 1 times with a remainder of 1.
The next digit of our result is 1. 
Result so far: 451.0
Subtract 2 from 3 to get 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

Going ahead to step 4:
The number 2 fits into 11 5 times, leaving a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 4515.0
The remainder is 1 after subtracting 10 from 11.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Advancing to step 5:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 45155.0
The remainder is 0 after subtracting 10 from 10.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Moving on to step 6:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 451554.0
Subtracting 8 from 8 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.

Going ahead to step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 451554.0
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.

Let's proceed to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 451554.0
If we take 0 away from 0, we end up 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 outcome is 451554.0, with a leftover of 0.0.
