We're dividing 12021842 by 388 
The aim is to understand the frequency of 388 in 12021842.

Moving on to step 1:
388 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 388

Advancing to step 2:
388 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 388

Moving on to step 3:
If we divide 120 by 388, we get 0 and a remainder of 120.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 120 after subtracting 0 from 120.
Grab the next digit (2) from the dividend, add it to 120, then carry on: 1202 / 388

Step 4:
If we divide 1202 by 388, we get 3 and a remainder of 38.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1164 from 1202 leaves us with 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 388

On to step 5:
388 can be fit into 381 0 times, resulting in a remainder of 381.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 381 to get 381.
Take the next digit (8) from the dividend and append it to 381, then repeat: 3818 / 388

Moving on to step 6:
When dividing 3818 by 388, we get 9 with a remainder of 326.
Use 9 as the next digit of our solution. 
Result so far: 309.0
Deduct 3492 from 3818 and we're left with 326.
Grab the next digit (4) from the dividend, add it to 326, then carry on: 3264 / 388

Step 7:
When dividing 3264 by 388, we get 8 with a remainder of 160.
The next digit of our result is 8. 
Result so far: 3098.0
If we subtract 3104 from 3264, we get 160.
Fetch the next digit (2) from the dividend, attach it to 160 and continue: 1602 / 388

Going ahead to step 8:
The number 388 fits into 1602 4 times, leaving a remainder of 50.
The number 4 becomes the next digit in our result. 
Result so far: 30984.0
If we take 1552 away from 1602, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
388 can be fit into 500 1 times, resulting in a remainder of 112.
Record the quotient 1 as the next digit in the result. 
Result so far: 30984.1
Subtracting 388 from 500 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 10:
When dividing 1120 by 388, we get 2 with a remainder of 344.
The next digit of our result is 2. 
Result so far: 30984.12
If we take 776 away from 1120, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 11:
When dividing 3440 by 388, we get 8 with a remainder of 336.
The number 8 becomes the next digit in our result. 
Result so far: 30984.128
If we subtract 3104 from 3440, we get 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Let's proceed to step 12:
388 can be fit into 3360 8 times, resulting in a remainder of 256.
Use 8 as the next digit of our solution. 
Result so far: 30984.1288
Subtracting 3104 from 3360 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.

Our division results in 30984.1288 with a remaining 0.00256.
