We're dividing 15362803 by 649 
We want to figure out the number of times 15362803 can be divided by 649.

Advancing to step 1:
649 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 649

On to step 2:
The number 649 fits into 15 0 times, leaving a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 649

Let's proceed to step 3:
The number 649 fits into 153 0 times, leaving a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 153 leaves us with 153.
Fetch the next digit (6) from the dividend, attach it to 153 and continue: 1536 / 649

Moving on to step 4:
1536 divided by 649 is 2 with a remainder of 238.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1298 away from 1536, we end up with 238.
Take the next digit (2) from the dividend and append it to 238, then repeat: 2382 / 649

Let's proceed to step 5:
649 can be fit into 2382 3 times, resulting in a remainder of 435.
The next digit of our result is 3. 
Result so far: 23.0
Subtracting 1947 from 2382 leaves us with 435.
Include the next digit (8) from the dividend after 435, then repeat: 4358 / 649

On to step 6:
When dividing 4358 by 649, we get 6 with a remainder of 464.
The number 6 becomes the next digit in our result. 
Result so far: 236.0
The remainder is 464 after subtracting 3894 from 4358.
Include the next digit (0) from the dividend after 464, then repeat: 4640 / 649

Moving on to step 7:
649 goes into 4640 7 times with a remainder of 97.
The next digit of our result is 7. 
Result so far: 2367.0
Subtracting 4543 from 4640 leaves us with 97.
Fetch the next digit (3) from the dividend, attach it to 97 and continue: 973 / 649

On to step 8:
If we divide 973 by 649, we get 1 and a remainder of 324.
Use 1 as the next digit of our solution. 
Result so far: 23671.0
The remainder is 324 after subtracting 649 from 973.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Moving on to step 9:
649 can be fit into 3240 4 times, resulting in a remainder of 644.
Use 4 as the next digit of our solution. 
Result so far: 23671.4
Subtract 2596 from 3240 to get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

On to step 10:
649 can be fit into 6440 9 times, resulting in a remainder of 599.
The next digit of our result is 9. 
Result so far: 23671.49
Subtract 5841 from 6440 to get 599.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5990, and continue the process.

Step 11:
649 goes into 5990 9 times with a remainder of 149.
Put 9 as the next digit of the answer. 
Result so far: 23671.499
If we take 5841 away from 5990, we end up with 149.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

The final result is 23671.499 with a remainder of 0.0149.
