We look at the division of 133369 by 38 
The aim is to understand the frequency of 38 in 133369.

Step 1:
38 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 38

Going ahead to step 2:
If we divide 13 by 38, we get 0 and a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 38

Going ahead to step 3:
38 can be fit into 133 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 19 after subtracting 114 from 133.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 38

Going ahead to step 4:
The number 38 fits into 193 5 times, leaving a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we subtract 190 from 193, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 38

Going ahead to step 5:
38 can be fit into 36 0 times, resulting in a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 350.0
Subtracting 0 from 36 leaves us with 36.
Append the next digit (9) from the dividend to 36 and continue with: 369 / 38

On to step 6:
The number 38 fits into 369 9 times, leaving a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 3509.0
Subtracting 342 from 369 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
If we divide 270 by 38, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 3509.7
If we subtract 266 from 270, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 38, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 3509.71
Deduct 38 from 40 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 38, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3509.71
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
When dividing 200 by 38, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 3509.7105
The remainder is 10 after subtracting 190 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
If we divide 100 by 38, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 3509.71052
The remainder is 24 after subtracting 76 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 12:
If we divide 240 by 38, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 3509.710526
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
38 goes into 120 3 times with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 3509.7105263
Deduct 114 from 120 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
When dividing 60 by 38, we get 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 3509.71052631
If we take 38 away from 60, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Our division results in 3509.71052631 with a remaining 2.2e-08.
