392817 ÷ 45 
We're looking to find how many times 45 goes into 392817.

Step 1:
3 divided by 45 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 45

Advancing to step 2:
45 goes into 39 0 times with a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (2) from the dividend, attach it to 39 and continue: 392 / 45

Step 3:
When dividing 392 by 45, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 360 from 392, we get 32.
Append the next digit (8) from the dividend to 32 and continue with: 328 / 45

Going ahead to step 4:
When dividing 328 by 45, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we subtract 315 from 328, we get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 45

On to step 5:
45 can be fit into 131 2 times, resulting in a remainder of 41.
Write down 2 as next digit of the result. 
Result so far: 872.0
If we subtract 90 from 131, we get 41.
Take the next digit (7) from the dividend and append it to 41, then repeat: 417 / 45

Going ahead to step 6:
When dividing 417 by 45, we get 9 with a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 8729.0
The remainder is 12 after subtracting 405 from 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
45 can be fit into 120 2 times, resulting in a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 8729.2
If we take 90 away from 120, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 45 is 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 8729.26
Deduct 270 from 300 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
The number 45 fits into 300 6 times, leaving a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 8729.266
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 8729.266 with a balance of 0.003.
