Let's divide 13498489 by 648
Let's see how many times 648 fits into 13498489.

Going ahead to step 1:
648 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 648

On to step 2:
If we divide 13 by 648, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 648

Step 3:
The number 648 fits into 134 0 times, leaving a remainder of 134.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 134, we end up with 134.
Include the next digit (9) from the dividend after 134, then repeat: 1349 / 648

Step 4:
648 goes into 1349 2 times with a remainder of 53.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 1296 away from 1349, we end up with 53.
Take the next digit (8) from the dividend and append it to 53, then repeat: 538 / 648

Moving on to step 5:
648 can be fit into 538 0 times, resulting in a remainder of 538.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 538, we end up with 538.
Take the next digit (4) from the dividend and append it to 538, then repeat: 5384 / 648

Advancing to step 6:
If we divide 5384 by 648, we get 8 and a remainder of 200.
The number 8 becomes the next digit in our result. 
Result so far: 208.0
If we subtract 5184 from 5384, we get 200.
Include the next digit (8) from the dividend after 200, then repeat: 2008 / 648

Step 7:
If we divide 2008 by 648, we get 3 and a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 2083.0
Subtracting 1944 from 2008 leaves us with 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 648

Let's proceed to step 8:
648 goes into 649 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 20831.0
If we take 648 away from 649, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
10 divided by 648 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 20831.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
If we divide 100 by 648, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 20831.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 20831.0, with a leftover of 0.1.
