We're dividing 396186 by 45 
Our goal is to divide 396186 by 45.

Going ahead to step 1:
If we divide 3 by 45, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 45

Step 2:
45 goes into 39 0 times with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 45

Moving on to step 3:
45 can be fit into 396 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 360 from 396, we get 36.
Include the next digit (1) from the dividend after 36, then repeat: 361 / 45

Going ahead to step 4:
45 goes into 361 8 times with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 88.0
Deduct 360 from 361 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 45

Step 5:
When dividing 18 by 45, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 880.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 45

Step 6:
186 divided by 45 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 8804.0
If we subtract 180 from 186, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
60 divided by 45 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 8804.1
Subtract 45 from 60 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.

Let's proceed to step 8:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 8804.13
The remainder is 15 after subtracting 135 from 150.
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:
The number 45 fits into 150 3 times, leaving a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 8804.133
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 8804.133, with a leftover of 0.0015.
