We look at the division of 648266 by 38 
The aim is to understand the frequency of 38 in 648266.

Step 1:
38 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 38

Let's proceed to step 2:
If we divide 64 by 38, we get 1 and a remainder of 26.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 38 from 64 to get 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 38

Moving on to step 3:
If we divide 268 by 38, we get 7 and a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 266 from 268 and we're left with 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 38

Step 4:
38 can be fit into 22 0 times, resulting in a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 170.0
If we take 0 away from 22, we end up with 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 38

On to step 5:
The number 38 fits into 226 5 times, leaving a remainder of 36.
The next digit of our result is 5. 
Result so far: 1705.0
Deduct 190 from 226 and we're left with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 38

Advancing to step 6:
38 can be fit into 366 9 times, resulting in a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 17059.0
If we take 342 away from 366, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
38 goes into 240 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 17059.6
If we subtract 228 from 240, we 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.

Going ahead to step 8:
When dividing 120 by 38, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 17059.63
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.

Let's proceed to step 9:
60 divided by 38 is 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 17059.631
Subtract 38 from 60 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
When dividing 220 by 38, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 17059.6315
If we subtract 190 from 220, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 11:
When dividing 300 by 38, we get 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 17059.63157
The remainder is 34 after subtracting 266 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
38 can be fit into 340 8 times, resulting in a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 17059.631578
The remainder is 36 after subtracting 304 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
38 goes into 360 9 times with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 17059.6315789
Subtracting 342 from 360 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
180 divided by 38 is 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 17059.63157894
Deduct 152 from 180 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 17059.63157894 and a remainder of 2.8e-08.
