12852115 ÷ 104 
Let's see how many times 104 fits into 12852115.

On to step 1:
If we divide 1 by 104, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 104

Let's proceed to step 2:
When dividing 12 by 104, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 104

Let's proceed to step 3:
128 divided by 104 is 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 104 away from 128, we end up with 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 104

On to step 4:
104 goes into 245 2 times with a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 208 from 245 to get 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 104

On to step 5:
104 can be fit into 372 3 times, resulting in a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtract 312 from 372 to get 60.
Bring next digit (1) of the dividend behind the 60 and repeat the process: 601 / 104

Let's proceed to step 6:
When dividing 601 by 104, we get 5 with a remainder of 81.
Use 5 as the next digit of our solution. 
Result so far: 1235.0
The remainder is 81 after subtracting 520 from 601.
Bring next digit (1) of the dividend behind the 81 and repeat the process: 811 / 104

Advancing to step 7:
The number 104 fits into 811 7 times, leaving a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 12357.0
If we take 728 away from 811, we end up with 83.
Take the next digit (5) from the dividend and append it to 83, then repeat: 835 / 104

Going ahead to step 8:
104 can be fit into 835 8 times, resulting in a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 123578.0
The remainder is 3 after subtracting 832 from 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
30 divided by 104 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 123578.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 104, we get 2 and a remainder of 92.
Put 2 as the next digit of the answer. 
Result so far: 123578.02
Subtract 208 from 300 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 11:
104 goes into 920 8 times with a remainder of 88.
Put 8 as the next digit of the answer. 
Result so far: 123578.028
If we subtract 832 from 920, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 12:
The number 104 fits into 880 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 123578.0288
The remainder is 48 after subtracting 832 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Our division results in 123578.0288 with a remaining 0.00048.
