Let's divide 99345783 by 309
Our goal is to divide 99345783 by 309.

Going ahead to step 1:
9 divided by 309 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 309

Let's proceed to step 2:
When dividing 99 by 309, we get 0 with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Fetch the next digit (3) from the dividend, attach it to 99 and continue: 993 / 309

Advancing to step 3:
309 goes into 993 3 times with a remainder of 66.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 927 from 993 leaves us with 66.
Take the next digit (4) from the dividend and append it to 66, then repeat: 664 / 309

Let's proceed to step 4:
The number 309 fits into 664 2 times, leaving a remainder of 46.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Deduct 618 from 664 and we're left with 46.
Bring next digit (5) of the dividend behind the 46 and repeat the process: 465 / 309

Going ahead to step 5:
309 goes into 465 1 times with a remainder of 156.
The next digit of our result is 1. 
Result so far: 321.0
The remainder is 156 after subtracting 309 from 465.
Take the next digit (7) from the dividend and append it to 156, then repeat: 1567 / 309

Step 6:
If we divide 1567 by 309, we get 5 and a remainder of 22.
The number 5 becomes the next digit in our result. 
Result so far: 3215.0
Subtracting 1545 from 1567 leaves us with 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 309

Going ahead to step 7:
When dividing 228 by 309, we get 0 with a remainder of 228.
Write down 0 as next digit of the result. 
Result so far: 32150.0
If we subtract 0 from 228, we get 228.
Take the next digit (3) from the dividend and append it to 228, then repeat: 2283 / 309

Let's proceed to step 8:
309 can be fit into 2283 7 times, resulting in a remainder of 120.
The number 7 becomes the next digit in our result. 
Result so far: 321507.0
The remainder is 120 after subtracting 2163 from 2283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 9:
If we divide 1200 by 309, we get 3 and a remainder of 273.
Use 3 as the next digit of our solution. 
Result so far: 321507.3
If we take 927 away from 1200, we end up with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Let's proceed to step 10:
The number 309 fits into 2730 8 times, leaving a remainder of 258.
Put 8 as the next digit of the answer. 
Result so far: 321507.38
If we subtract 2472 from 2730, we get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 11:
309 can be fit into 2580 8 times, resulting in a remainder of 108.
Put 8 as the next digit of the answer. 
Result so far: 321507.388
Subtracting 2472 from 2580 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final result is 321507.388 with a remainder of 0.0108.
