Let's divide 72566481 by 309
We're looking to find how many times 309 goes into 72566481.

Step 1:
309 goes into 7 0 times with 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.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 309

On to step 2:
The number 309 fits into 72 0 times, leaving a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Take the next digit (5) from the dividend and append it to 72, then repeat: 725 / 309

Going ahead to step 3:
309 can be fit into 725 2 times, resulting in a remainder of 107.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 618 from 725 and we're left with 107.
Fetch the next digit (6) from the dividend, attach it to 107 and continue: 1076 / 309

Let's proceed to step 4:
When dividing 1076 by 309, we get 3 with a remainder of 149.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 927 from 1076, we get 149.
Include the next digit (6) from the dividend after 149, then repeat: 1496 / 309

On to step 5:
309 can be fit into 1496 4 times, resulting in a remainder of 260.
The number 4 becomes the next digit in our result. 
Result so far: 234.0
Deduct 1236 from 1496 and we're left with 260.
Bring next digit (4) of the dividend behind the 260 and repeat the process: 2604 / 309

Going ahead to step 6:
When dividing 2604 by 309, we get 8 with a remainder of 132.
The next digit of our result is 8. 
Result so far: 2348.0
Subtracting 2472 from 2604 leaves us with 132.
Grab the next digit (8) from the dividend, add it to 132, then carry on: 1328 / 309

Step 7:
309 can be fit into 1328 4 times, resulting in a remainder of 92.
The number 4 becomes the next digit in our result. 
Result so far: 23484.0
If we subtract 1236 from 1328, we get 92.
Take the next digit (1) from the dividend and append it to 92, then repeat: 921 / 309

Advancing to step 8:
921 divided by 309 is 2 with a remainder of 303.
Write down 2 as next digit of the result. 
Result so far: 234842.0
If we subtract 618 from 921, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 9:
The number 309 fits into 3030 9 times, leaving a remainder of 249.
The next digit of our result is 9. 
Result so far: 234842.9
The remainder is 249 after subtracting 2781 from 3030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Let's proceed to step 10:
If we divide 2490 by 309, we get 8 and a remainder of 18.
The next digit of our result is 8. 
Result so far: 234842.98
If we subtract 2472 from 2490, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
309 goes into 180 0 times with a remainder of 180.
The next digit of our result is 0. 
Result so far: 234842.98
Deduct 0 from 180 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 12:
The number 309 fits into 1800 5 times, leaving a remainder of 255.
Record the quotient 5 as the next digit in the result. 
Result so far: 234842.9805
Subtracting 1545 from 1800 leaves us with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 13:
2550 divided by 309 is 8 with a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 234842.98058
If we subtract 2472 from 2550, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 14:
The number 309 fits into 780 2 times, leaving a remainder of 162.
The next digit of our result is 2. 
Result so far: 234842.980582
If we subtract 618 from 780, we get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 15:
If we divide 1620 by 309, we get 5 and a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 234842.9805825
Subtracting 1545 from 1620 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 16:
When dividing 750 by 309, we get 2 with a remainder of 132.
Put 2 as the next digit of the answer. 
Result so far: 234842.98058252
The remainder is 132 after subtracting 618 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

After the division, we end up with 234842.98058252 and a remainder of 1.32e-07.
