We're dividing 39379164 by 306 
The aim is to understand the frequency of 306 in 39379164.

Let's proceed to step 1:
When dividing 3 by 306, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 306

Advancing to step 2:
If we divide 39 by 306, we get 0 and a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 306

Going ahead to step 3:
306 can be fit into 393 1 times, resulting in a remainder of 87.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 306 from 393 to get 87.
Include the next digit (7) from the dividend after 87, then repeat: 877 / 306

Going ahead to step 4:
877 divided by 306 is 2 with a remainder of 265.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 612 away from 877, we end up with 265.
Bring next digit (9) of the dividend behind the 265 and repeat the process: 2659 / 306

Going ahead to step 5:
306 can be fit into 2659 8 times, resulting in a remainder of 211.
Write down 8 as next digit of the result. 
Result so far: 128.0
The remainder is 211 after subtracting 2448 from 2659.
Take the next digit (1) from the dividend and append it to 211, then repeat: 2111 / 306

On to step 6:
306 can be fit into 2111 6 times, resulting in a remainder of 275.
Record the quotient 6 as the next digit in the result. 
Result so far: 1286.0
If we subtract 1836 from 2111, we get 275.
Grab the next digit (6) from the dividend, add it to 275, then carry on: 2756 / 306

Moving on to step 7:
306 goes into 2756 9 times with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 12869.0
If we take 2754 away from 2756, we end up with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 306

Step 8:
If we divide 24 by 306, we get 0 and a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 128690.0
Deduct 0 from 24 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 9:
306 goes into 240 0 times with a remainder of 240.
Record the quotient 0 as the next digit in the result. 
Result so far: 128690.0
The remainder is 240 after subtracting 0 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 10:
The number 306 fits into 2400 7 times, leaving a remainder of 258.
The next digit of our result is 7. 
Result so far: 128690.07
Subtract 2142 from 2400 to 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.

Let's proceed to step 11:
306 can be fit into 2580 8 times, resulting in a remainder of 132.
The number 8 becomes the next digit in our result. 
Result so far: 128690.078
The remainder is 132 after subtracting 2448 from 2580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 12:
The number 306 fits into 1320 4 times, leaving a remainder of 96.
The next digit of our result is 4. 
Result so far: 128690.0784
If we take 1224 away from 1320, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
306 goes into 960 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 128690.07843
The remainder is 42 after subtracting 918 from 960.
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 14:
If we divide 420 by 306, we get 1 and a remainder of 114.
Record the quotient 1 as the next digit in the result. 
Result so far: 128690.078431
The remainder is 114 after subtracting 306 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Going ahead to step 15:
If we divide 1140 by 306, we get 3 and a remainder of 222.
Use 3 as the next digit of our solution. 
Result so far: 128690.0784313
Deduct 918 from 1140 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 16:
306 can be fit into 2220 7 times, resulting in a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 128690.07843137
The remainder is 78 after subtracting 2142 from 2220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

In conclusion, the division gives 128690.07843137 with a balance of 7.8e-08.
