We divide 3911474 by 388
The aim is to understand the frequency of 388 in 3911474.

Going ahead to step 1:
When dividing 3 by 388, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 388

Step 2:
The number 388 fits into 39 0 times, leaving a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 388

Advancing to step 3:
The number 388 fits into 391 1 times, leaving a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 388 from 391 to get 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 388

Advancing to step 4:
The number 388 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 31, we get 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 388

Moving on to step 5:
388 goes into 314 0 times with a remainder of 314.
Write down 0 as next digit of the result. 
Result so far: 100.0
The remainder is 314 after subtracting 0 from 314.
Append the next digit (7) from the dividend to 314 and continue with: 3147 / 388

Going ahead to step 6:
The number 388 fits into 3147 8 times, leaving a remainder of 43.
Use 8 as the next digit of our solution. 
Result so far: 1008.0
The remainder is 43 after subtracting 3104 from 3147.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 388

Advancing to step 7:
If we divide 434 by 388, we get 1 and a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 10081.0
If we take 388 away from 434, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 8:
388 goes into 460 1 times with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 10081.1
The remainder is 72 after subtracting 388 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
If we divide 720 by 388, we get 1 and a remainder of 332.
The number 1 becomes the next digit in our result. 
Result so far: 10081.11
The remainder is 332 after subtracting 388 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final result is 10081.11 with a remainder of 0.332.
