We're dividing 30608521 by 388 
The aim is to understand the frequency of 388 in 30608521.

Moving on to step 1:
388 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 388

Going ahead to step 2:
The number 388 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 388

Advancing to step 3:
388 can be fit into 306 0 times, resulting in a remainder of 306.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 306 and we're left with 306.
Grab the next digit (0) from the dividend, add it to 306, then carry on: 3060 / 388

Step 4:
If we divide 3060 by 388, we get 7 and a remainder of 344.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 2716 from 3060 leaves us with 344.
Bring next digit (8) of the dividend behind the 344 and repeat the process: 3448 / 388

On to step 5:
3448 divided by 388 is 8 with a remainder of 344.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Subtracting 3104 from 3448 leaves us with 344.
Fetch the next digit (5) from the dividend, attach it to 344 and continue: 3445 / 388

Going ahead to step 6:
388 goes into 3445 8 times with a remainder of 341.
Put 8 as the next digit of the answer. 
Result so far: 788.0
If we take 3104 away from 3445, we end up with 341.
Fetch the next digit (2) from the dividend, attach it to 341 and continue: 3412 / 388

Going ahead to step 7:
3412 divided by 388 is 8 with a remainder of 308.
Use 8 as the next digit of our solution. 
Result so far: 7888.0
Deduct 3104 from 3412 and we're left with 308.
Fetch the next digit (1) from the dividend, attach it to 308 and continue: 3081 / 388

Advancing to step 8:
When dividing 3081 by 388, we get 7 with a remainder of 365.
Put 7 as the next digit of the answer. 
Result so far: 78887.0
The remainder is 365 after subtracting 2716 from 3081.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 9:
388 goes into 3650 9 times with a remainder of 158.
Record the quotient 9 as the next digit in the result. 
Result so far: 78887.9
If we subtract 3492 from 3650, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 10:
If we divide 1580 by 388, we get 4 and a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 78887.94
The remainder is 28 after subtracting 1552 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
When dividing 280 by 388, we get 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 78887.94
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 12:
If we divide 2800 by 388, we get 7 and a remainder of 84.
The next digit of our result is 7. 
Result so far: 78887.9407
Subtract 2716 from 2800 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 13:
When dividing 840 by 388, we get 2 with a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 78887.94072
Subtracting 776 from 840 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
388 can be fit into 640 1 times, resulting in a remainder of 252.
The number 1 becomes the next digit in our result. 
Result so far: 78887.940721
Subtract 388 from 640 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Step 15:
If we divide 2520 by 388, we get 6 and a remainder of 192.
The next digit of our result is 6. 
Result so far: 78887.9407216
Subtract 2328 from 2520 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 16:
If we divide 1920 by 388, we get 4 and a remainder of 368.
The number 4 becomes the next digit in our result. 
Result so far: 78887.94072164
The remainder is 368 after subtracting 1552 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

The final result is 78887.94072164 with a remainder of 3.68e-07.
