Let's divide 12903040 by 844
We're looking to find how many times 844 goes into 12903040.

Moving on to step 1:
1 divided by 844 is 0 with 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.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 844

Moving on to step 2:
12 divided by 844 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 844

Advancing to step 3:
The number 844 fits into 129 0 times, leaving a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 129 and we're left with 129.
Bring next digit (0) of the dividend behind the 129 and repeat the process: 1290 / 844

Going ahead to step 4:
If we divide 1290 by 844, we get 1 and a remainder of 446.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 446 after subtracting 844 from 1290.
Take the next digit (3) from the dividend and append it to 446, then repeat: 4463 / 844

On to step 5:
The number 844 fits into 4463 5 times, leaving a remainder of 243.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 4220 from 4463 and we're left with 243.
Include the next digit (0) from the dividend after 243, then repeat: 2430 / 844

Moving on to step 6:
844 goes into 2430 2 times with a remainder of 742.
Use 2 as the next digit of our solution. 
Result so far: 152.0
Subtract 1688 from 2430 to get 742.
Bring next digit (4) of the dividend behind the 742 and repeat the process: 7424 / 844

Moving on to step 7:
7424 divided by 844 is 8 with a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 1528.0
If we take 6752 away from 7424, we end up with 672.
Append the next digit (0) from the dividend to 672 and continue with: 6720 / 844

Advancing to step 8:
844 can be fit into 6720 7 times, resulting in a remainder of 812.
Use 7 as the next digit of our solution. 
Result so far: 15287.0
Subtracting 5908 from 6720 leaves us with 812.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8120, and continue the process.

Going ahead to step 9:
844 can be fit into 8120 9 times, resulting in a remainder of 524.
Write down 9 as next digit of the result. 
Result so far: 15287.9
Subtract 7596 from 8120 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 10:
844 can be fit into 5240 6 times, resulting in a remainder of 176.
Use 6 as the next digit of our solution. 
Result so far: 15287.96
The remainder is 176 after subtracting 5064 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
When dividing 1760 by 844, we get 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 15287.962
If we subtract 1688 from 1760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 12:
844 goes into 720 0 times with a remainder of 720.
Put 0 as the next digit of the answer. 
Result so far: 15287.962
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

On to step 13:
844 goes into 7200 8 times with a remainder of 448.
The number 8 becomes the next digit in our result. 
Result so far: 15287.96208
Subtracting 6752 from 7200 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 14:
4480 divided by 844 is 5 with a remainder of 260.
Write down 5 as next digit of the result. 
Result so far: 15287.962085
Subtract 4220 from 4480 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 15:
844 goes into 2600 3 times with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 15287.9620853
If we subtract 2532 from 2600, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 16:
680 divided by 844 is 0 with a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 15287.9620853
If we subtract 0 from 680, we get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Our division results in 15287.9620853 with a remaining 6.8e-07.
