We're dividing 723966 by 45 
Let's see how many times 45 fits into 723966.

Moving on to step 1:
The number 45 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 45

Step 2:
If we divide 72 by 45, we get 1 and a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 72 and we're left with 27.
Append the next digit (3) from the dividend to 27 and continue with: 273 / 45

Going ahead to step 3:
45 can be fit into 273 6 times, resulting in a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 270 from 273 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 45

Advancing to step 4:
45 can be fit into 39 0 times, resulting in a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 160.0
Deduct 0 from 39 and we're left with 39.
Append the next digit (6) from the dividend to 39 and continue with: 396 / 45

Step 5:
45 goes into 396 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 1608.0
If we take 360 away from 396, we end up with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 45

Advancing to step 6:
If we divide 366 by 45, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 16088.0
Subtracting 360 from 366 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
When dividing 60 by 45, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 16088.1
Deduct 45 from 60 and we're left 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.

Advancing to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 16088.13
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.

Advancing to step 9:
When dividing 150 by 45, we get 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 16088.133
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.

The final outcome is 16088.133, with a leftover of 0.0015.
