9128520 divided by 309 
Let's see how many times 309 fits into 9128520.

Let's proceed to step 1:
If we divide 9 by 309, we get 0 and 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.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 309

Let's proceed to step 2:
The number 309 fits into 91 0 times, leaving a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Include the next digit (2) from the dividend after 91, then repeat: 912 / 309

Advancing to step 3:
If we divide 912 by 309, we get 2 and a remainder of 294.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 618 from 912 to get 294.
Take the next digit (8) from the dividend and append it to 294, then repeat: 2948 / 309

Going ahead to step 4:
309 goes into 2948 9 times with a remainder of 167.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 2781 from 2948 to get 167.
Grab the next digit (5) from the dividend, add it to 167, then carry on: 1675 / 309

On to step 5:
If we divide 1675 by 309, we get 5 and a remainder of 130.
Use 5 as the next digit of our solution. 
Result so far: 295.0
Deduct 1545 from 1675 and we're left with 130.
Fetch the next digit (2) from the dividend, attach it to 130 and continue: 1302 / 309

Let's proceed to step 6:
If we divide 1302 by 309, we get 4 and a remainder of 66.
The next digit of our result is 4. 
Result so far: 2954.0
Deduct 1236 from 1302 and we're left with 66.
Include the next digit (0) from the dividend after 66, then repeat: 660 / 309

On to step 7:
309 goes into 660 2 times with a remainder of 42.
The next digit of our result is 2. 
Result so far: 29542.0
If we subtract 618 from 660, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 8:
When dividing 420 by 309, we get 1 with a remainder of 111.
Put 1 as the next digit of the answer. 
Result so far: 29542.1
Deduct 309 from 420 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 9:
1110 divided by 309 is 3 with a remainder of 183.
The number 3 becomes the next digit in our result. 
Result so far: 29542.13
Subtracting 927 from 1110 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 10:
309 can be fit into 1830 5 times, resulting in a remainder of 285.
The next digit of our result is 5. 
Result so far: 29542.135
If we take 1545 away from 1830, we end up with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Let's proceed to step 11:
When dividing 2850 by 309, we get 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 29542.1359
If we subtract 2781 from 2850, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
309 can be fit into 690 2 times, resulting in a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 29542.13592
The remainder is 72 after subtracting 618 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
The number 309 fits into 720 2 times, leaving a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 29542.135922
If we subtract 618 from 720, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Our division results in 29542.135922 with a remaining 1.02e-05.
