We divide 49979934 by 309
The aim is to understand the frequency of 309 in 49979934.

Step 1:
The number 309 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 309

Advancing to step 2:
309 goes into 49 0 times with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Fetch the next digit (9) from the dividend, attach it to 49 and continue: 499 / 309

Let's proceed to step 3:
The number 309 fits into 499 1 times, leaving a remainder of 190.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 190 after subtracting 309 from 499.
Bring next digit (7) of the dividend behind the 190 and repeat the process: 1907 / 309

Advancing to step 4:
1907 divided by 309 is 6 with a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we subtract 1854 from 1907, we get 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 309

Advancing to step 5:
If we divide 539 by 309, we get 1 and a remainder of 230.
Use 1 as the next digit of our solution. 
Result so far: 161.0
The remainder is 230 after subtracting 309 from 539.
Bring next digit (9) of the dividend behind the 230 and repeat the process: 2309 / 309

Let's proceed to step 6:
309 can be fit into 2309 7 times, resulting in a remainder of 146.
Put 7 as the next digit of the answer. 
Result so far: 1617.0
Subtracting 2163 from 2309 leaves us with 146.
Append the next digit (3) from the dividend to 146 and continue with: 1463 / 309

Moving on to step 7:
If we divide 1463 by 309, we get 4 and a remainder of 227.
Put 4 as the next digit of the answer. 
Result so far: 16174.0
The remainder is 227 after subtracting 1236 from 1463.
Bring next digit (4) of the dividend behind the 227 and repeat the process: 2274 / 309

Moving on to step 8:
309 can be fit into 2274 7 times, resulting in a remainder of 111.
The next digit of our result is 7. 
Result so far: 161747.0
Deduct 2163 from 2274 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.

Let's proceed to step 9:
The number 309 fits into 1110 3 times, leaving a remainder of 183.
Write down 3 as next digit of the result. 
Result so far: 161747.3
Deduct 927 from 1110 and we're left 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.

Moving on to step 10:
When dividing 1830 by 309, we get 5 with a remainder of 285.
Use 5 as the next digit of our solution. 
Result so far: 161747.35
Subtracting 1545 from 1830 leaves us 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:
If we divide 2850 by 309, we get 9 and a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 161747.359
The remainder is 69 after subtracting 2781 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 12:
When dividing 690 by 309, we get 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 161747.3592
Subtract 618 from 690 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
720 divided by 309 is 2 with a remainder of 102.
Put 2 as the next digit of the answer. 
Result so far: 161747.35922
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 161747.35922 with a remaining 0.000102.
