We look at the division of 238303 by 38 
The aim is to understand the frequency of 38 in 238303.

Advancing to step 1:
The number 38 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 38

On to step 2:
If we divide 23 by 38, we get 0 and a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Grab the next digit (8) from the dividend, add it to 23, then carry on: 238 / 38

Let's proceed to step 3:
If we divide 238 by 38, we get 6 and a remainder of 10.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 228 from 238 to get 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 38

Going ahead to step 4:
103 divided by 38 is 2 with a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 62.0
Deduct 76 from 103 and we're left with 27.
Fetch the next digit (0) from the dividend, attach it to 27 and continue: 270 / 38

Let's proceed to step 5:
270 divided by 38 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 627.0
If we subtract 266 from 270, we get 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 38

Let's proceed to step 6:
The number 38 fits into 43 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 6271.0
If we subtract 38 from 43, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
38 can be fit into 50 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 6271.1
If we subtract 38 from 50, 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.

Step 8:
38 goes into 120 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 6271.13
If we take 114 away from 120, we end up 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.

Moving on to step 9:
38 goes into 60 1 times with a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 6271.131
Deduct 38 from 60 and we're left 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.

Step 10:
38 can be fit into 220 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 6271.1315
Subtracting 190 from 220 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
The number 38 fits into 300 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 6271.13157
Subtracting 266 from 300 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
38 goes into 340 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 6271.131578
Deduct 304 from 340 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
360 divided by 38 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 6271.1315789
If we take 342 away from 360, we end up 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.

Let's proceed to step 14:
180 divided by 38 is 4 with a remainder of 28.
The next digit of our result is 4. 
Result so far: 6271.13157894
Subtract 152 from 180 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final result is 6271.13157894 with a remainder of 2.8e-08.
