We look at the division of 71091060 by 648 
Let's see how many times 648 fits into 71091060.

Going ahead to step 1:
If we divide 7 by 648, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 648

On to step 2:
648 goes into 71 0 times with a remainder of 71.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Append the next digit (0) from the dividend to 71 and continue with: 710 / 648

Advancing to step 3:
648 goes into 710 1 times with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 648 from 710 and we're left with 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 648

Going ahead to step 4:
629 divided by 648 is 0 with a remainder of 629.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 629, we end up with 629.
Fetch the next digit (1) from the dividend, attach it to 629 and continue: 6291 / 648

Going ahead to step 5:
648 goes into 6291 9 times with a remainder of 459.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we take 5832 away from 6291, we end up with 459.
Fetch the next digit (0) from the dividend, attach it to 459 and continue: 4590 / 648

Let's proceed to step 6:
648 goes into 4590 7 times with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 1097.0
Subtract 4536 from 4590 to get 54.
Bring next digit (6) of the dividend behind the 54 and repeat the process: 546 / 648

Advancing to step 7:
648 goes into 546 0 times with a remainder of 546.
Put 0 as the next digit of the answer. 
Result so far: 10970.0
If we subtract 0 from 546, we get 546.
Take the next digit (0) from the dividend and append it to 546, then repeat: 5460 / 648

Step 8:
648 goes into 5460 8 times with a remainder of 276.
Record the quotient 8 as the next digit in the result. 
Result so far: 109708.0
Subtracting 5184 from 5460 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 9:
2760 divided by 648 is 4 with a remainder of 168.
The next digit of our result is 4. 
Result so far: 109708.4
The remainder is 168 after subtracting 2592 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 10:
When dividing 1680 by 648, we get 2 with a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 109708.42
Subtracting 1296 from 1680 leaves us with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 11:
When dividing 3840 by 648, we get 5 with a remainder of 600.
Write down 5 as next digit of the result. 
Result so far: 109708.425
Subtracting 3240 from 3840 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Advancing to step 12:
6000 divided by 648 is 9 with a remainder of 168.
Write down 9 as next digit of the result. 
Result so far: 109708.4259
Subtract 5832 from 6000 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 13:
648 goes into 1680 2 times with a remainder of 384.
Record the quotient 2 as the next digit in the result. 
Result so far: 109708.42592
If we subtract 1296 from 1680, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 14:
648 can be fit into 3840 5 times, resulting in a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 109708.425925
Deduct 3240 from 3840 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 15:
The number 648 fits into 6000 9 times, leaving a remainder of 168.
The number 9 becomes the next digit in our result. 
Result so far: 109708.4259259
Subtracting 5832 from 6000 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 16:
When dividing 1680 by 648, we get 2 with a remainder of 384.
Use 2 as the next digit of our solution. 
Result so far: 109708.42592592
If we take 1296 away from 1680, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

In conclusion, the division gives 109708.42592592 with a balance of 3.84e-07.
