We're dividing 804723 by 45 
We want to figure out the number of times 804723 can be divided by 45.

Advancing to step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 45

On to step 2:
80 divided by 45 is 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 45 from 80 leaves us with 35.
Grab the next digit (4) from the dividend, add it to 35, then carry on: 354 / 45

Going ahead to step 3:
45 goes into 354 7 times with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtracting 315 from 354 leaves us with 39.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 45

Let's proceed to step 4:
If we divide 397 by 45, we get 8 and a remainder of 37.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Deduct 360 from 397 and we're left with 37.
Bring next digit (2) of the dividend behind the 37 and repeat the process: 372 / 45

Moving on to step 5:
The number 45 fits into 372 8 times, leaving a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 1788.0
Subtract 360 from 372 to get 12.
Grab the next digit (3) from the dividend, add it to 12, then carry on: 123 / 45

Moving on to step 6:
When dividing 123 by 45, we get 2 with a remainder of 33.
The next digit of our result is 2. 
Result so far: 17882.0
Subtract 90 from 123 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
330 divided by 45 is 7 with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 17882.7
Subtracting 315 from 330 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.

Going ahead to step 8:
45 goes into 150 3 times with a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 17882.73
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.

Going ahead to step 9:
45 goes into 150 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 17882.733
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 final result is 17882.733 with a remainder of 0.0015.
