17684912 ÷ 306 
The aim is to understand the frequency of 306 in 17684912.

Advancing to step 1:
306 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 306

On to step 2:
17 divided by 306 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (6) from the dividend and append it to 17, then repeat: 176 / 306

Advancing to step 3:
If we divide 176 by 306, we get 0 and a remainder of 176.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 176 to get 176.
Bring next digit (8) of the dividend behind the 176 and repeat the process: 1768 / 306

On to step 4:
306 goes into 1768 5 times with a remainder of 238.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 1530 from 1768 and we're left with 238.
Bring next digit (4) of the dividend behind the 238 and repeat the process: 2384 / 306

Step 5:
2384 divided by 306 is 7 with a remainder of 242.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
The remainder is 242 after subtracting 2142 from 2384.
Include the next digit (9) from the dividend after 242, then repeat: 2429 / 306

Let's proceed to step 6:
306 goes into 2429 7 times with a remainder of 287.
Put 7 as the next digit of the answer. 
Result so far: 577.0
If we subtract 2142 from 2429, we get 287.
Fetch the next digit (1) from the dividend, attach it to 287 and continue: 2871 / 306

On to step 7:
2871 divided by 306 is 9 with a remainder of 117.
Write down 9 as next digit of the result. 
Result so far: 5779.0
Subtract 2754 from 2871 to get 117.
Fetch the next digit (2) from the dividend, attach it to 117 and continue: 1172 / 306

On to step 8:
1172 divided by 306 is 3 with a remainder of 254.
Write down 3 as next digit of the result. 
Result so far: 57793.0
If we subtract 918 from 1172, we get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

On to step 9:
306 goes into 2540 8 times with a remainder of 92.
The next digit of our result is 8. 
Result so far: 57793.8
If we subtract 2448 from 2540, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 10:
306 goes into 920 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 57793.83
If we subtract 918 from 920, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
306 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 57793.83
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
The number 306 fits into 200 0 times, leaving a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 57793.83
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 57793.83 with a remainder of 0.002.
