Let's divide 39520112 by 872
We're looking to find how many times 872 goes into 39520112.

On to step 1:
If we divide 3 by 872, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 872

Going ahead to step 2:
872 can be fit into 39 0 times, resulting in a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 872

On to step 3:
If we divide 395 by 872, we get 0 and a remainder of 395.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 395 leaves us with 395.
Append the next digit (2) from the dividend to 395 and continue with: 3952 / 872

Moving on to step 4:
If we divide 3952 by 872, we get 4 and a remainder of 464.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 464 after subtracting 3488 from 3952.
Append the next digit (0) from the dividend to 464 and continue with: 4640 / 872

Let's proceed to step 5:
When dividing 4640 by 872, we get 5 with a remainder of 280.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
The remainder is 280 after subtracting 4360 from 4640.
Append the next digit (1) from the dividend to 280 and continue with: 2801 / 872

Moving on to step 6:
872 goes into 2801 3 times with a remainder of 185.
Record the quotient 3 as the next digit in the result. 
Result so far: 453.0
If we subtract 2616 from 2801, we get 185.
Append the next digit (1) from the dividend to 185 and continue with: 1851 / 872

On to step 7:
872 can be fit into 1851 2 times, resulting in a remainder of 107.
Write down 2 as next digit of the result. 
Result so far: 4532.0
If we subtract 1744 from 1851, we get 107.
Append the next digit (2) from the dividend to 107 and continue with: 1072 / 872

Advancing to step 8:
872 goes into 1072 1 times with a remainder of 200.
Use 1 as the next digit of our solution. 
Result so far: 45321.0
The remainder is 200 after subtracting 872 from 1072.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Step 9:
872 can be fit into 2000 2 times, resulting in a remainder of 256.
Use 2 as the next digit of our solution. 
Result so far: 45321.2
The remainder is 256 after subtracting 1744 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 10:
872 can be fit into 2560 2 times, resulting in a remainder of 816.
The next digit of our result is 2. 
Result so far: 45321.22
The remainder is 816 after subtracting 1744 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

After the division, we end up with 45321.22 and a remainder of 0.816.
