We look at the division of 99065389 by 648 
We want to divide 99065389 by 648.

On to step 1:
648 goes into 9 0 times with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 648

Step 2:
If we divide 99 by 648, we get 0 and a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Bring next digit (0) of the dividend behind the 99 and repeat the process: 990 / 648

Moving on to step 3:
648 can be fit into 990 1 times, resulting in a remainder of 342.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 648 from 990, we get 342.
Include the next digit (6) from the dividend after 342, then repeat: 3426 / 648

Advancing to step 4:
648 goes into 3426 5 times with a remainder of 186.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtracting 3240 from 3426 leaves us with 186.
Fetch the next digit (5) from the dividend, attach it to 186 and continue: 1865 / 648

On to step 5:
648 can be fit into 1865 2 times, resulting in a remainder of 569.
Put 2 as the next digit of the answer. 
Result so far: 152.0
Subtract 1296 from 1865 to get 569.
Append the next digit (3) from the dividend to 569 and continue with: 5693 / 648

On to step 6:
The number 648 fits into 5693 8 times, leaving a remainder of 509.
The next digit of our result is 8. 
Result so far: 1528.0
Subtracting 5184 from 5693 leaves us with 509.
Fetch the next digit (8) from the dividend, attach it to 509 and continue: 5098 / 648

Step 7:
5098 divided by 648 is 7 with a remainder of 562.
The number 7 becomes the next digit in our result. 
Result so far: 15287.0
If we subtract 4536 from 5098, we get 562.
Append the next digit (9) from the dividend to 562 and continue with: 5629 / 648

Going ahead to step 8:
5629 divided by 648 is 8 with a remainder of 445.
The next digit of our result is 8. 
Result so far: 152878.0
If we subtract 5184 from 5629, we get 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Step 9:
If we divide 4450 by 648, we get 6 and a remainder of 562.
The next digit of our result is 6. 
Result so far: 152878.6
The remainder is 562 after subtracting 3888 from 4450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

On to step 10:
When dividing 5620 by 648, we get 8 with a remainder of 436.
Write down 8 as next digit of the result. 
Result so far: 152878.68
The remainder is 436 after subtracting 5184 from 5620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

Moving on to step 11:
The number 648 fits into 4360 6 times, leaving a remainder of 472.
The next digit of our result is 6. 
Result so far: 152878.686
If we subtract 3888 from 4360, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 12:
648 can be fit into 4720 7 times, resulting in a remainder of 184.
Record the quotient 7 as the next digit in the result. 
Result so far: 152878.6867
If we subtract 4536 from 4720, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 13:
The number 648 fits into 1840 2 times, leaving a remainder of 544.
Put 2 as the next digit of the answer. 
Result so far: 152878.68672
Subtract 1296 from 1840 to get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Going ahead to step 14:
648 can be fit into 5440 8 times, resulting in a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 152878.686728
If we subtract 5184 from 5440, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 15:
If we divide 2560 by 648, we get 3 and a remainder of 616.
The number 3 becomes the next digit in our result. 
Result so far: 152878.6867283
Subtract 1944 from 2560 to get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Let's proceed to step 16:
The number 648 fits into 6160 9 times, leaving a remainder of 328.
The number 9 becomes the next digit in our result. 
Result so far: 152878.68672839
If we take 5832 away from 6160, we end up with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

The quotient of the division is 152878.68672839, and the remainder is 3.28e-07.
