We're dividing 4499661 by 388 
The aim is to understand the frequency of 388 in 4499661.

Let's proceed to step 1:
388 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 388

Advancing to step 2:
The number 388 fits into 44 0 times, leaving a remainder of 44.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 44, we get 44.
Take the next digit (9) from the dividend and append it to 44, then repeat: 449 / 388

Step 3:
If we divide 449 by 388, we get 1 and a remainder of 61.
The next digit of our result is 1. 
Result so far: 1.0
If we take 388 away from 449, we end up with 61.
Append the next digit (9) from the dividend to 61 and continue with: 619 / 388

Moving on to step 4:
The number 388 fits into 619 1 times, leaving a remainder of 231.
The next digit of our result is 1. 
Result so far: 11.0
Subtracting 388 from 619 leaves us with 231.
Grab the next digit (6) from the dividend, add it to 231, then carry on: 2316 / 388

On to step 5:
If we divide 2316 by 388, we get 5 and a remainder of 376.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtracting 1940 from 2316 leaves us with 376.
Append the next digit (6) from the dividend to 376 and continue with: 3766 / 388

Step 6:
3766 divided by 388 is 9 with a remainder of 274.
The next digit of our result is 9. 
Result so far: 1159.0
The remainder is 274 after subtracting 3492 from 3766.
Include the next digit (1) from the dividend after 274, then repeat: 2741 / 388

On to step 7:
388 can be fit into 2741 7 times, resulting in a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 11597.0
If we subtract 2716 from 2741, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
388 goes into 250 0 times with a remainder of 250.
Write down 0 as next digit of the result. 
Result so far: 11597.0
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Advancing to step 9:
2500 divided by 388 is 6 with a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 11597.06
The remainder is 172 after subtracting 2328 from 2500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 10:
388 goes into 1720 4 times with a remainder of 168.
Put 4 as the next digit of the answer. 
Result so far: 11597.064
Subtract 1552 from 1720 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 11:
388 goes into 1680 4 times with a remainder of 128.
The number 4 becomes the next digit in our result. 
Result so far: 11597.0644
If we subtract 1552 from 1680, 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.

Our division results in 11597.0644 with a remaining 0.00128.
