97394648 divided by 309 
Our goal is to divide 97394648 by 309.

Let's proceed to step 1:
309 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 309

Let's proceed to step 2:
97 divided by 309 is 0 with a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Bring next digit (3) of the dividend behind the 97 and repeat the process: 973 / 309

Advancing to step 3:
309 can be fit into 973 3 times, resulting in a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 927 from 973, we get 46.
Grab the next digit (9) from the dividend, add it to 46, then carry on: 469 / 309

On to step 4:
When dividing 469 by 309, we get 1 with a remainder of 160.
Use 1 as the next digit of our solution. 
Result so far: 31.0
If we take 309 away from 469, we end up with 160.
Include the next digit (4) from the dividend after 160, then repeat: 1604 / 309

Step 5:
309 goes into 1604 5 times with a remainder of 59.
Write down 5 as next digit of the result. 
Result so far: 315.0
Subtract 1545 from 1604 to get 59.
Include the next digit (6) from the dividend after 59, then repeat: 596 / 309

Step 6:
309 can be fit into 596 1 times, resulting in a remainder of 287.
Put 1 as the next digit of the answer. 
Result so far: 3151.0
The remainder is 287 after subtracting 309 from 596.
Grab the next digit (4) from the dividend, add it to 287, then carry on: 2874 / 309

Going ahead to step 7:
309 can be fit into 2874 9 times, resulting in a remainder of 93.
The next digit of our result is 9. 
Result so far: 31519.0
The remainder is 93 after subtracting 2781 from 2874.
Take the next digit (8) from the dividend and append it to 93, then repeat: 938 / 309

Step 8:
309 can be fit into 938 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 315193.0
If we take 927 away from 938, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
When dividing 110 by 309, we get 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 315193.0
Subtracting 0 from 110 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
1100 divided by 309 is 3 with a remainder of 173.
The number 3 becomes the next digit in our result. 
Result so far: 315193.03
Subtracting 927 from 1100 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Advancing to step 11:
309 can be fit into 1730 5 times, resulting in a remainder of 185.
The number 5 becomes the next digit in our result. 
Result so far: 315193.035
The remainder is 185 after subtracting 1545 from 1730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 12:
The number 309 fits into 1850 5 times, leaving a remainder of 305.
The number 5 becomes the next digit in our result. 
Result so far: 315193.0355
If we take 1545 away from 1850, we end up with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

After the division, we end up with 315193.0355 and a remainder of 0.00305.
