We divide 3015838 by 10
We're looking to find how many times 10 goes into 3015838.

Step 1:
The number 10 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 10

Advancing to step 2:
10 can be fit into 30 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 30 from 30 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 10

Going ahead to step 3:
1 divided by 10 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 30.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 10

Moving on to step 4:
If we divide 15 by 10, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 301.0
Subtracting 10 from 15 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 10

Let's proceed to step 5:
The number 10 fits into 58 5 times, leaving a remainder of 8.
The next digit of our result is 5. 
Result so far: 3015.0
The remainder is 8 after subtracting 50 from 58.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 10

On to step 6:
10 goes into 83 8 times with a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 30158.0
Subtracting 80 from 83 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 10

Advancing to step 7:
10 goes into 38 3 times with a remainder of 8.
The next digit of our result is 3. 
Result so far: 301583.0
Deduct 30 from 38 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 10 fits into 80 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 301583.8
If we subtract 80 from 80, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 301583.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
10 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 301583.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 301583.8 with a remainder of 0.0.
