We're dividing 97860245 by 309 
We want to figure out the number of times 97860245 can be divided by 309.

Moving on to step 1:
The number 309 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 309

Let's proceed to step 2:
97 divided by 309 is 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Grab the next digit (8) from the dividend, add it to 97, then carry on: 978 / 309

On to step 3:
978 divided by 309 is 3 with a remainder of 51.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 51 after subtracting 927 from 978.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 309

Moving on to step 4:
309 can be fit into 516 1 times, resulting in a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 309 from 516 to get 207.
Fetch the next digit (0) from the dividend, attach it to 207 and continue: 2070 / 309

Step 5:
The number 309 fits into 2070 6 times, leaving a remainder of 216.
The next digit of our result is 6. 
Result so far: 316.0
If we subtract 1854 from 2070, we get 216.
Fetch the next digit (2) from the dividend, attach it to 216 and continue: 2162 / 309

On to step 6:
2162 divided by 309 is 6 with a remainder of 308.
The number 6 becomes the next digit in our result. 
Result so far: 3166.0
Subtract 1854 from 2162 to get 308.
Take the next digit (4) from the dividend and append it to 308, then repeat: 3084 / 309

Advancing to step 7:
309 can be fit into 3084 9 times, resulting in a remainder of 303.
Write down 9 as next digit of the result. 
Result so far: 31669.0
Deduct 2781 from 3084 and we're left with 303.
Append the next digit (5) from the dividend to 303 and continue with: 3035 / 309

Going ahead to step 8:
The number 309 fits into 3035 9 times, leaving a remainder of 254.
Use 9 as the next digit of our solution. 
Result so far: 316699.0
Subtracting 2781 from 3035 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Let's proceed to step 9:
If we divide 2540 by 309, we get 8 and a remainder of 68.
The next digit of our result is 8. 
Result so far: 316699.8
Deduct 2472 from 2540 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 10:
If we divide 680 by 309, we get 2 and a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 316699.82
The remainder is 62 after subtracting 618 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 11:
620 divided by 309 is 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 316699.822
If we take 618 away from 620, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 316699.822 with a balance of 0.0002.
