We look at the division of 5098915 by 648 
Our goal is to divide 5098915 by 648.

Going ahead to step 1:
5 divided by 648 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 648

Step 2:
50 divided by 648 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 50, we end up with 50.
Include the next digit (9) from the dividend after 50, then repeat: 509 / 648

Step 3:
648 can be fit into 509 0 times, resulting in a remainder of 509.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 509 and we're left with 509.
Bring next digit (8) of the dividend behind the 509 and repeat the process: 5098 / 648

Step 4:
648 goes into 5098 7 times with a remainder of 562.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 4536 from 5098 leaves us with 562.
Fetch the next digit (9) from the dividend, attach it to 562 and continue: 5629 / 648

On to step 5:
648 can be fit into 5629 8 times, resulting in a remainder of 445.
Put 8 as the next digit of the answer. 
Result so far: 78.0
Subtracting 5184 from 5629 leaves us with 445.
Include the next digit (1) from the dividend after 445, then repeat: 4451 / 648

Let's proceed to step 6:
If we divide 4451 by 648, we get 6 and a remainder of 563.
The number 6 becomes the next digit in our result. 
Result so far: 786.0
If we subtract 3888 from 4451, we get 563.
Append the next digit (5) from the dividend to 563 and continue with: 5635 / 648

Going ahead to step 7:
The number 648 fits into 5635 8 times, leaving a remainder of 451.
The number 8 becomes the next digit in our result. 
Result so far: 7868.0
Subtracting 5184 from 5635 leaves us with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Let's proceed to step 8:
648 can be fit into 4510 6 times, resulting in a remainder of 622.
Use 6 as the next digit of our solution. 
Result so far: 7868.6
If we take 3888 away from 4510, we end up with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Moving on to step 9:
When dividing 6220 by 648, we get 9 with a remainder of 388.
Record the quotient 9 as the next digit in the result. 
Result so far: 7868.69
Deduct 5832 from 6220 and we're left with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 10:
648 can be fit into 3880 5 times, resulting in a remainder of 640.
Write down 5 as next digit of the result. 
Result so far: 7868.695
Subtract 3240 from 3880 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 11:
648 goes into 6400 9 times with a remainder of 568.
The number 9 becomes the next digit in our result. 
Result so far: 7868.6959
Subtract 5832 from 6400 to get 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Let's proceed to step 12:
648 can be fit into 5680 8 times, resulting in a remainder of 496.
Write down 8 as next digit of the result. 
Result so far: 7868.69598
Subtracting 5184 from 5680 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 13:
If we divide 4960 by 648, we get 7 and a remainder of 424.
Use 7 as the next digit of our solution. 
Result so far: 7868.695987
Subtracting 4536 from 4960 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Moving on to step 14:
648 goes into 4240 6 times with a remainder of 352.
Write down 6 as next digit of the result. 
Result so far: 7868.6959876
If we subtract 3888 from 4240, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 15:
If we divide 3520 by 648, we get 5 and a remainder of 280.
Use 5 as the next digit of our solution. 
Result so far: 7868.69598765
The remainder is 280 after subtracting 3240 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 7868.69598765 with a remainder of 2.8e-07.
