30688559 ÷ 186 
The aim is to understand the frequency of 186 in 30688559.

Moving on to step 1:
If we divide 3 by 186, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 186

On to step 2:
186 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 186

Moving on to step 3:
306 divided by 186 is 1 with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 186 away from 306, we end up with 120.
Append the next digit (8) from the dividend to 120 and continue with: 1208 / 186

On to step 4:
If we divide 1208 by 186, we get 6 and a remainder of 92.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 1116 away from 1208, we end up with 92.
Include the next digit (8) from the dividend after 92, then repeat: 928 / 186

On to step 5:
186 goes into 928 4 times with a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 164.0
If we subtract 744 from 928, we get 184.
Bring next digit (5) of the dividend behind the 184 and repeat the process: 1845 / 186

Let's proceed to step 6:
If we divide 1845 by 186, we get 9 and a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 1649.0
If we subtract 1674 from 1845, we get 171.
Grab the next digit (5) from the dividend, add it to 171, then carry on: 1715 / 186

Moving on to step 7:
If we divide 1715 by 186, we get 9 and a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 16499.0
If we take 1674 away from 1715, we end up with 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 186

On to step 8:
If we divide 419 by 186, we get 2 and a remainder of 47.
Put 2 as the next digit of the answer. 
Result so far: 164992.0
Deduct 372 from 419 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 9:
186 can be fit into 470 2 times, resulting in a remainder of 98.
Put 2 as the next digit of the answer. 
Result so far: 164992.2
If we subtract 372 from 470, we get 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Let's proceed to step 10:
The number 186 fits into 980 5 times, leaving a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 164992.25
Subtract 930 from 980 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 11:
The number 186 fits into 500 2 times, leaving a remainder of 128.
Use 2 as the next digit of our solution. 
Result so far: 164992.252
If we subtract 372 from 500, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 12:
186 goes into 1280 6 times with a remainder of 164.
Write down 6 as next digit of the result. 
Result so far: 164992.2526
If we take 1116 away from 1280, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Going ahead to step 13:
186 can be fit into 1640 8 times, resulting in a remainder of 152.
Put 8 as the next digit of the answer. 
Result so far: 164992.25268
Deduct 1488 from 1640 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 14:
1520 divided by 186 is 8 with a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 164992.252688
Subtract 1488 from 1520 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 164992.252688 with a remainder of 3.2e-06.
