We divide 68530309 by 72
We want to divide 68530309 by 72.

Advancing to step 1:
The number 72 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 72

On to step 2:
68 divided by 72 is 0 with a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 72

On to step 3:
When dividing 685 by 72, we get 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 648 from 685, we get 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 72

Going ahead to step 4:
If we divide 373 by 72, we get 5 and a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Deduct 360 from 373 and we're left with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 72

On to step 5:
If we divide 130 by 72, we get 1 and a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 951.0
If we subtract 72 from 130, we get 58.
Bring next digit (3) of the dividend behind the 58 and repeat the process: 583 / 72

Moving on to step 6:
The number 72 fits into 583 8 times, leaving a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 9518.0
The remainder is 7 after subtracting 576 from 583.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 72

On to step 7:
72 can be fit into 70 0 times, resulting in a remainder of 70.
The next digit of our result is 0. 
Result so far: 95180.0
Subtract 0 from 70 to get 70.
Include the next digit (9) from the dividend after 70, then repeat: 709 / 72

Let's proceed to step 8:
709 divided by 72 is 9 with a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 951809.0
If we subtract 648 from 709, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 9:
The number 72 fits into 610 8 times, leaving a remainder of 34.
The next digit of our result is 8. 
Result so far: 951809.8
If we subtract 576 from 610, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
If we divide 340 by 72, we get 4 and a remainder of 52.
The next digit of our result is 4. 
Result so far: 951809.84
Deduct 288 from 340 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
If we divide 520 by 72, we get 7 and a remainder of 16.
The next digit of our result is 7. 
Result so far: 951809.847
If we subtract 504 from 520, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 12:
When dividing 160 by 72, we get 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 951809.8472
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
72 can be fit into 160 2 times, resulting in a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 951809.84722
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 951809.84722, and the remainder is 1.6e-05.
