852116 divided by 45 
Our goal is to divide 852116 by 45.

Moving on to step 1:
If we divide 8 by 45, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 45

Moving on to step 2:
85 divided by 45 is 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 40 after subtracting 45 from 85.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 45

On to step 3:
45 goes into 402 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 360 from 402 to get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 45

On to step 4:
421 divided by 45 is 9 with a remainder of 16.
The next digit of our result is 9. 
Result so far: 189.0
Subtract 405 from 421 to get 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 45

Step 5:
161 divided by 45 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 1893.0
Deduct 135 from 161 and we're left with 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 45

Moving on to step 6:
45 can be fit into 266 5 times, resulting in a remainder of 41.
Write down 5 as next digit of the result. 
Result so far: 18935.0
Subtract 225 from 266 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
45 can be fit into 410 9 times, resulting in a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 18935.9
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
50 divided by 45 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 18935.91
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
If we divide 50 by 45, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 18935.911
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 18935.911 with a remainder of 0.0005.
