72306560 divided by 192 
We want to figure out the number of times 72306560 can be divided by 192.

Step 1:
If we divide 7 by 192, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 192

Step 2:
If we divide 72 by 192, 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 (3) from the dividend after 72, then repeat: 723 / 192

Moving on to step 3:
The number 192 fits into 723 3 times, leaving a remainder of 147.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 576 from 723 and we're left with 147.
Include the next digit (0) from the dividend after 147, then repeat: 1470 / 192

Moving on to step 4:
1470 divided by 192 is 7 with a remainder of 126.
The next digit of our result is 7. 
Result so far: 37.0
If we subtract 1344 from 1470, we get 126.
Fetch the next digit (6) from the dividend, attach it to 126 and continue: 1266 / 192

Moving on to step 5:
192 goes into 1266 6 times with a remainder of 114.
The next digit of our result is 6. 
Result so far: 376.0
If we take 1152 away from 1266, we end up with 114.
Include the next digit (5) from the dividend after 114, then repeat: 1145 / 192

On to step 6:
The number 192 fits into 1145 5 times, leaving a remainder of 185.
Write down 5 as next digit of the result. 
Result so far: 3765.0
Subtract 960 from 1145 to get 185.
Take the next digit (6) from the dividend and append it to 185, then repeat: 1856 / 192

Advancing to step 7:
192 goes into 1856 9 times with a remainder of 128.
The next digit of our result is 9. 
Result so far: 37659.0
Subtract 1728 from 1856 to get 128.
Take the next digit (0) from the dividend and append it to 128, then repeat: 1280 / 192

On to step 8:
When dividing 1280 by 192, we get 6 with a remainder of 128.
The number 6 becomes the next digit in our result. 
Result so far: 376596.0
Subtract 1152 from 1280 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Going ahead to step 9:
When dividing 1280 by 192, we get 6 with a remainder of 128.
Record the quotient 6 as the next digit in the result. 
Result so far: 376596.6
Subtract 1152 from 1280 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 10:
If we divide 1280 by 192, we get 6 and a remainder of 128.
Put 6 as the next digit of the answer. 
Result so far: 376596.66
If we subtract 1152 from 1280, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 376596.66 with a remainder of 0.128.
