We look at the division of 838104 by 45 
We're looking to find how many times 45 goes into 838104.

Advancing to step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 45

On to step 2:
If we divide 83 by 45, we get 1 and a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 45 from 83, we get 38.
Take the next digit (8) from the dividend and append it to 38, then repeat: 388 / 45

On to step 3:
45 can be fit into 388 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
Deduct 360 from 388 and we're left with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 45

Going ahead to step 4:
281 divided by 45 is 6 with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 186.0
Subtract 270 from 281 to get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 45

Advancing to step 5:
45 can be fit into 110 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 1862.0
Subtracting 90 from 110 leaves us with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 45

On to step 6:
45 can be fit into 204 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 18624.0
Subtracting 180 from 204 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
45 can be fit into 240 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 18624.5
If we take 225 away from 240, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
If we divide 150 by 45, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 18624.53
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
150 divided by 45 is 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 18624.533
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 18624.533 with a remainder of 0.0015.
