72576373 divided by 309 
We're looking to find how many times 309 goes into 72576373.

Let's proceed to step 1:
The number 309 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 309

Going ahead to step 2:
309 can be fit into 72 0 times, resulting in a remainder of 72.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 309

Let's proceed to step 3:
725 divided by 309 is 2 with a remainder of 107.
The next digit of our result is 2. 
Result so far: 2.0
If we take 618 away from 725, we end up with 107.
Append the next digit (7) from the dividend to 107 and continue with: 1077 / 309

Let's proceed to step 4:
1077 divided by 309 is 3 with a remainder of 150.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
If we take 927 away from 1077, we end up with 150.
Append the next digit (6) from the dividend to 150 and continue with: 1506 / 309

Going ahead to step 5:
309 goes into 1506 4 times with a remainder of 270.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
If we subtract 1236 from 1506, we get 270.
Grab the next digit (3) from the dividend, add it to 270, then carry on: 2703 / 309

On to step 6:
2703 divided by 309 is 8 with a remainder of 231.
Record the quotient 8 as the next digit in the result. 
Result so far: 2348.0
Deduct 2472 from 2703 and we're left with 231.
Append the next digit (7) from the dividend to 231 and continue with: 2317 / 309

On to step 7:
309 can be fit into 2317 7 times, resulting in a remainder of 154.
Record the quotient 7 as the next digit in the result. 
Result so far: 23487.0
If we subtract 2163 from 2317, we get 154.
Take the next digit (3) from the dividend and append it to 154, then repeat: 1543 / 309

Let's proceed to step 8:
When dividing 1543 by 309, we get 4 with a remainder of 307.
The number 4 becomes the next digit in our result. 
Result so far: 234874.0
Subtract 1236 from 1543 to get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Going ahead to step 9:
309 goes into 3070 9 times with a remainder of 289.
Put 9 as the next digit of the answer. 
Result so far: 234874.9
Deduct 2781 from 3070 and we're left with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

Step 10:
309 can be fit into 2890 9 times, resulting in a remainder of 109.
The next digit of our result is 9. 
Result so far: 234874.99
Subtracting 2781 from 2890 leaves us with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

After the division, we end up with 234874.99 and a remainder of 0.109.
