72139654 divided by 720 
We're looking to find how many times 720 goes into 72139654.

Step 1:
The number 720 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 720

On to step 2:
If we divide 72 by 720, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (1) from the dividend after 72, then repeat: 721 / 720

Let's proceed to step 3:
If we divide 721 by 720, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 720 from 721.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 720

Advancing to step 4:
720 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 720

Going ahead to step 5:
139 divided by 720 is 0 with a remainder of 139.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtracting 0 from 139 leaves us with 139.
Fetch the next digit (6) from the dividend, attach it to 139 and continue: 1396 / 720

Advancing to step 6:
If we divide 1396 by 720, we get 1 and a remainder of 676.
Put 1 as the next digit of the answer. 
Result so far: 1001.0
Subtracting 720 from 1396 leaves us with 676.
Append the next digit (5) from the dividend to 676 and continue with: 6765 / 720

Step 7:
720 goes into 6765 9 times with a remainder of 285.
The number 9 becomes the next digit in our result. 
Result so far: 10019.0
Subtracting 6480 from 6765 leaves us with 285.
Take the next digit (4) from the dividend and append it to 285, then repeat: 2854 / 720

Moving on to step 8:
2854 divided by 720 is 3 with a remainder of 694.
Put 3 as the next digit of the answer. 
Result so far: 100193.0
The remainder is 694 after subtracting 2160 from 2854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Step 9:
When dividing 6940 by 720, we get 9 with a remainder of 460.
Put 9 as the next digit of the answer. 
Result so far: 100193.9
If we subtract 6480 from 6940, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 10:
720 can be fit into 4600 6 times, resulting in a remainder of 280.
Record the quotient 6 as the next digit in the result. 
Result so far: 100193.96
Deduct 4320 from 4600 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Let's proceed to step 11:
2800 divided by 720 is 3 with a remainder of 640.
The number 3 becomes the next digit in our result. 
Result so far: 100193.963
The remainder is 640 after subtracting 2160 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 12:
When dividing 6400 by 720, we get 8 with a remainder of 640.
The number 8 becomes the next digit in our result. 
Result so far: 100193.9638
If we subtract 5760 from 6400, we 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.

On to step 13:
If we divide 6400 by 720, we get 8 and a remainder of 640.
Write down 8 as next digit of the result. 
Result so far: 100193.96388
Deduct 5760 from 6400 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

The final result is 100193.96388 with a remainder of 0.00064.
