We're dividing 89159019 by 648 
Let's see how many times 648 fits into 89159019.

On to step 1:
648 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 648

Moving on to step 2:
648 can be fit into 89 0 times, resulting in a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Take the next digit (1) from the dividend and append it to 89, then repeat: 891 / 648

On to step 3:
If we divide 891 by 648, we get 1 and a remainder of 243.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 648 from 891 leaves us with 243.
Grab the next digit (5) from the dividend, add it to 243, then carry on: 2435 / 648

Let's proceed to step 4:
The number 648 fits into 2435 3 times, leaving a remainder of 491.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1944 from 2435 and we're left with 491.
Include the next digit (9) from the dividend after 491, then repeat: 4919 / 648

Step 5:
If we divide 4919 by 648, we get 7 and a remainder of 383.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
If we subtract 4536 from 4919, we get 383.
Include the next digit (0) from the dividend after 383, then repeat: 3830 / 648

Going ahead to step 6:
If we divide 3830 by 648, we get 5 and a remainder of 590.
Put 5 as the next digit of the answer. 
Result so far: 1375.0
Subtract 3240 from 3830 to get 590.
Take the next digit (1) from the dividend and append it to 590, then repeat: 5901 / 648

Moving on to step 7:
5901 divided by 648 is 9 with a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 13759.0
Deduct 5832 from 5901 and we're left with 69.
Grab the next digit (9) from the dividend, add it to 69, then carry on: 699 / 648

On to step 8:
648 goes into 699 1 times with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 137591.0
If we subtract 648 from 699, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Moving on to step 9:
If we divide 510 by 648, we get 0 and a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 137591.0
The remainder is 510 after subtracting 0 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 10:
648 can be fit into 5100 7 times, resulting in a remainder of 564.
Record the quotient 7 as the next digit in the result. 
Result so far: 137591.07
If we take 4536 away from 5100, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Let's proceed to step 11:
648 goes into 5640 8 times with a remainder of 456.
Record the quotient 8 as the next digit in the result. 
Result so far: 137591.078
If we take 5184 away from 5640, we end up with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 12:
648 goes into 4560 7 times with a remainder of 24.
Put 7 as the next digit of the answer. 
Result so far: 137591.0787
Deduct 4536 from 4560 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
648 can be fit into 240 0 times, resulting in a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 137591.0787
Subtracting 0 from 240 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 14:
If we divide 2400 by 648, we get 3 and a remainder of 456.
The number 3 becomes the next digit in our result. 
Result so far: 137591.078703
Subtracting 1944 from 2400 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 15:
When dividing 4560 by 648, we get 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 137591.0787037
Subtract 4536 from 4560 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 16:
If we divide 240 by 648, we get 0 and a remainder of 240.
Use 0 as the next digit of our solution. 
Result so far: 137591.0787037
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The final result is 137591.0787037 with a remainder of 2.4e-07.
