366686 ÷ 45 
Our goal is to divide 366686 by 45.

Step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 45

Step 2:
36 divided by 45 is 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 36, we get 36.
Fetch the next digit (6) from the dividend, attach it to 36 and continue: 366 / 45

Advancing to step 3:
When dividing 366 by 45, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 360 from 366 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 45

Let's proceed to step 4:
66 divided by 45 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Deduct 45 from 66 and we're left with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 45

Step 5:
The number 45 fits into 218 4 times, leaving a remainder of 38.
The next digit of our result is 4. 
Result so far: 814.0
Subtracting 180 from 218 leaves us with 38.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 45

Going ahead to step 6:
45 can be fit into 386 8 times, resulting in a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 8148.0
Subtracting 360 from 386 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
45 goes into 260 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 8148.5
Subtracting 225 from 260 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
When dividing 350 by 45, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 8148.57
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 8148.577
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 8148.577 and a remainder of 0.0035.
