903453 ÷ 6 
We want to figure out the number of times 903453 can be divided by 6.

On to step 1:
The number 6 fits into 9 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
If we take 6 away from 9, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 6

Moving on to step 2:
6 can be fit into 30 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 30 from 30 leaves us with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 6

Advancing to step 3:
3 divided by 6 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 150.0
Subtract 0 from 3 to get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 6

On to step 4:
6 can be fit into 34 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 1505.0
The remainder is 4 after subtracting 30 from 34.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 6

On to step 5:
6 goes into 45 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 15057.0
Subtract 42 from 45 to get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 6

On to step 6:
6 goes into 33 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 150575.0
The remainder is 3 after subtracting 30 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 6 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 150575.5
If we subtract 30 from 30, 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 8:
If we divide 0 by 6, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 150575.5
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.

Going ahead to step 9:
The number 6 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 150575.5
The remainder is 0 after subtracting 0 from 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 150575.5 with a remainder of 0.0.
