We look at the division of 30930039 by 309 
Our goal is to divide 30930039 by 309.

Going ahead to step 1:
When dividing 3 by 309, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 309

Moving on to step 2:
When dividing 30 by 309, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 309

Step 3:
309 goes into 309 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 309 away from 309, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 309

Advancing to step 4:
If we divide 3 by 309, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 3 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 309

On to step 5:
309 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 30 and we're left with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 309

Let's proceed to step 6:
300 divided by 309 is 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 1000.0
Subtracting 0 from 300 leaves us with 300.
Include the next digit (3) from the dividend after 300, then repeat: 3003 / 309

Moving on to step 7:
3003 divided by 309 is 9 with a remainder of 222.
Write down 9 as next digit of the result. 
Result so far: 10009.0
Subtract 2781 from 3003 to get 222.
Grab the next digit (9) from the dividend, add it to 222, then carry on: 2229 / 309

Step 8:
When dividing 2229 by 309, we get 7 with a remainder of 66.
The next digit of our result is 7. 
Result so far: 100097.0
Subtracting 2163 from 2229 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
309 can be fit into 660 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 100097.2
Deduct 618 from 660 and we're left with 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 10:
309 can be fit into 420 1 times, resulting in a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 100097.21
The remainder is 111 after subtracting 309 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Advancing to step 11:
1110 divided by 309 is 3 with a remainder of 183.
Write down 3 as next digit of the result. 
Result so far: 100097.213
If we take 927 away from 1110, we end up 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 12:
1830 divided by 309 is 5 with a remainder of 285.
The number 5 becomes the next digit in our result. 
Result so far: 100097.2135
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.

Advancing to step 13:
When dividing 2850 by 309, we get 9 with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 100097.21359
Subtract 2781 from 2850 to 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.

Advancing to step 14:
The number 309 fits into 690 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 100097.213592
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.

Step 15:
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: 100097.2135922
The remainder is 102 after subtracting 618 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

The quotient of the division is 100097.2135922, and the remainder is 1.02e-06.
