We're dividing 839094 by 45 
Our goal is to divide 839094 by 45.

Moving on to step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 45

Moving on to step 2:
45 can be fit into 83 1 times, resulting in a remainder of 38.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 45 from 83 leaves us with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 45

Going ahead to step 3:
45 goes into 389 8 times with a remainder of 29.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 29 after subtracting 360 from 389.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 45

Let's proceed to step 4:
45 can be fit into 290 6 times, resulting in a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 186.0
Subtract 270 from 290 to get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 45

Step 5:
209 divided by 45 is 4 with a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 1864.0
Subtracting 180 from 209 leaves us with 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 45

Going ahead to step 6:
294 divided by 45 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 18646.0
Deduct 270 from 294 and we're left 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.

On to step 7:
If we divide 240 by 45, we get 5 and a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 18646.5
Subtracting 225 from 240 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.

Moving on to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
The next digit of our result is 3. 
Result so far: 18646.53
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.

Moving on to step 9:
If we divide 150 by 45, we get 3 and a remainder of 15.
The next digit of our result is 3. 
Result so far: 18646.533
If we take 135 away from 150, 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.

The quotient of the division is 18646.533, and the remainder is 0.0015.
