72715490 divided by 668 
We want to figure out the number of times 72715490 can be divided by 668.

Step 1:
668 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 668

Advancing to step 2:
The number 668 fits into 72 0 times, leaving a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Append the next digit (7) from the dividend to 72 and continue with: 727 / 668

On to step 3:
668 goes into 727 1 times with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 668 from 727, we get 59.
Grab the next digit (1) from the dividend, add it to 59, then carry on: 591 / 668

Let's proceed to step 4:
When dividing 591 by 668, we get 0 with a remainder of 591.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 591, we end up with 591.
Bring next digit (5) of the dividend behind the 591 and repeat the process: 5915 / 668

Step 5:
If we divide 5915 by 668, we get 8 and a remainder of 571.
Put 8 as the next digit of the answer. 
Result so far: 108.0
The remainder is 571 after subtracting 5344 from 5915.
Include the next digit (4) from the dividend after 571, then repeat: 5714 / 668

Step 6:
When dividing 5714 by 668, we get 8 with a remainder of 370.
Put 8 as the next digit of the answer. 
Result so far: 1088.0
If we subtract 5344 from 5714, we get 370.
Take the next digit (9) from the dividend and append it to 370, then repeat: 3709 / 668

Moving on to step 7:
The number 668 fits into 3709 5 times, leaving a remainder of 369.
Record the quotient 5 as the next digit in the result. 
Result so far: 10885.0
Subtracting 3340 from 3709 leaves us with 369.
Grab the next digit (0) from the dividend, add it to 369, then carry on: 3690 / 668

Going ahead to step 8:
3690 divided by 668 is 5 with a remainder of 350.
The number 5 becomes the next digit in our result. 
Result so far: 108855.0
The remainder is 350 after subtracting 3340 from 3690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Let's proceed to step 9:
The number 668 fits into 3500 5 times, leaving a remainder of 160.
Put 5 as the next digit of the answer. 
Result so far: 108855.5
The remainder is 160 after subtracting 3340 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 10:
If we divide 1600 by 668, we get 2 and a remainder of 264.
Put 2 as the next digit of the answer. 
Result so far: 108855.52
Subtracting 1336 from 1600 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 11:
The number 668 fits into 2640 3 times, leaving a remainder of 636.
Write down 3 as next digit of the result. 
Result so far: 108855.523
If we take 2004 away from 2640, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Step 12:
668 can be fit into 6360 9 times, resulting in a remainder of 348.
The next digit of our result is 9. 
Result so far: 108855.5239
If we take 6012 away from 6360, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 13:
If we divide 3480 by 668, we get 5 and a remainder of 140.
The number 5 becomes the next digit in our result. 
Result so far: 108855.52395
If we take 3340 away from 3480, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 14:
668 can be fit into 1400 2 times, resulting in a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 108855.523952
Subtracting 1336 from 1400 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 15:
The number 668 fits into 640 0 times, leaving a remainder of 640.
Put 0 as the next digit of the answer. 
Result so far: 108855.523952
Subtract 0 from 640 to get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Moving on to step 16:
6400 divided by 668 is 9 with a remainder of 388.
Put 9 as the next digit of the answer. 
Result so far: 108855.52395209
Subtracting 6012 from 6400 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

After the division, we end up with 108855.52395209 and a remainder of 3.88e-07.
