We look at the division of 339904 by 453 
We're looking to find how many times 453 goes into 339904.

On to step 1:
453 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 453

Step 2:
33 divided by 453 is 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 453

Moving on to step 3:
453 can be fit into 339 0 times, resulting in a remainder of 339.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 339 after subtracting 0 from 339.
Bring next digit (9) of the dividend behind the 339 and repeat the process: 3399 / 453

Step 4:
When dividing 3399 by 453, we get 7 with a remainder of 228.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtract 3171 from 3399 to get 228.
Bring next digit (0) of the dividend behind the 228 and repeat the process: 2280 / 453

Going ahead to step 5:
453 goes into 2280 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 75.0
Subtracting 2265 from 2280 leaves us with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 453

Let's proceed to step 6:
453 goes into 154 0 times with a remainder of 154.
Use 0 as the next digit of our solution. 
Result so far: 750.0
The remainder is 154 after subtracting 0 from 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 7:
1540 divided by 453 is 3 with a remainder of 181.
Record the quotient 3 as the next digit in the result. 
Result so far: 750.3
The remainder is 181 after subtracting 1359 from 1540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Advancing to step 8:
If we divide 1810 by 453, we get 3 and a remainder of 451.
The next digit of our result is 3. 
Result so far: 750.33
If we subtract 1359 from 1810, we get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

After the division, we end up with 750.33 and a remainder of 0.451.
