We look at the division of 10128514 by 306 
The aim is to understand the frequency of 306 in 10128514.

Moving on to step 1:
306 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 306

Going ahead to step 2:
If we divide 10 by 306, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 306

Moving on to step 3:
When dividing 101 by 306, we get 0 with a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 101, we get 101.
Take the next digit (2) from the dividend and append it to 101, then repeat: 1012 / 306

Advancing to step 4:
The number 306 fits into 1012 3 times, leaving a remainder of 94.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 918 from 1012 and we're left with 94.
Include the next digit (8) from the dividend after 94, then repeat: 948 / 306

On to step 5:
306 can be fit into 948 3 times, resulting in a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtracting 918 from 948 leaves us with 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 306

Let's proceed to step 6:
305 divided by 306 is 0 with a remainder of 305.
Put 0 as the next digit of the answer. 
Result so far: 330.0
If we subtract 0 from 305, we get 305.
Fetch the next digit (1) from the dividend, attach it to 305 and continue: 3051 / 306

Advancing to step 7:
3051 divided by 306 is 9 with a remainder of 297.
Write down 9 as next digit of the result. 
Result so far: 3309.0
If we take 2754 away from 3051, we end up with 297.
Append the next digit (4) from the dividend to 297 and continue with: 2974 / 306

Moving on to step 8:
The number 306 fits into 2974 9 times, leaving a remainder of 220.
Use 9 as the next digit of our solution. 
Result so far: 33099.0
Deduct 2754 from 2974 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 9:
306 goes into 2200 7 times with a remainder of 58.
Record the quotient 7 as the next digit in the result. 
Result so far: 33099.7
Subtracting 2142 from 2200 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 10:
306 goes into 580 1 times with a remainder of 274.
Write down 1 as next digit of the result. 
Result so far: 33099.71
The remainder is 274 after subtracting 306 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

On to step 11:
The number 306 fits into 2740 8 times, leaving a remainder of 292.
Write down 8 as next digit of the result. 
Result so far: 33099.718
The remainder is 292 after subtracting 2448 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 12:
The number 306 fits into 2920 9 times, leaving a remainder of 166.
Put 9 as the next digit of the answer. 
Result so far: 33099.7189
Subtract 2754 from 2920 to get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 13:
If we divide 1660 by 306, we get 5 and a remainder of 130.
Record the quotient 5 as the next digit in the result. 
Result so far: 33099.71895
Subtract 1530 from 1660 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 14:
306 can be fit into 1300 4 times, resulting in a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 33099.718954
Subtract 1224 from 1300 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 15:
When dividing 760 by 306, we get 2 with a remainder of 148.
The next digit of our result is 2. 
Result so far: 33099.7189542
Subtract 612 from 760 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 16:
306 goes into 1480 4 times with a remainder of 256.
Record the quotient 4 as the next digit in the result. 
Result so far: 33099.71895424
Subtracting 1224 from 1480 leaves us with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

In conclusion, the division gives 33099.71895424 with a balance of 2.56e-07.
