We look at the division of 475974 by 38 
The aim is to understand the frequency of 38 in 475974.

Advancing to step 1:
When dividing 4 by 38, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 38

On to step 2:
When dividing 47 by 38, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 38 from 47, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 38

Moving on to step 3:
When dividing 95 by 38, we get 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 76 from 95 to get 19.
Fetch the next digit (9) from the dividend, attach it to 19 and continue: 199 / 38

On to step 4:
38 can be fit into 199 5 times, resulting in a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 125.0
Subtract 190 from 199 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 38

Let's proceed to step 5:
When dividing 97 by 38, we get 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 1252.0
Subtract 76 from 97 to get 21.
Grab the next digit (4) from the dividend, add it to 21, then carry on: 214 / 38

Step 6:
If we divide 214 by 38, we get 5 and a remainder of 24.
The next digit of our result is 5. 
Result so far: 12525.0
If we subtract 190 from 214, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
240 divided by 38 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 12525.6
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.

Moving on to step 8:
The number 38 fits into 120 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 12525.63
If we subtract 114 from 120, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
38 can be fit into 60 1 times, resulting in a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 12525.631
Subtracting 38 from 60 leaves us 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.

Moving on to step 10:
38 goes into 220 5 times with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 12525.6315
If we take 190 away from 220, we end up 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:
38 goes into 300 7 times with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 12525.63157
Deduct 266 from 300 and we're left 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 can be fit into 340 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 12525.631578
Subtracting 304 from 340 leaves us 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.

Going ahead to step 13:
When dividing 360 by 38, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 12525.6315789
Subtract 342 from 360 to get 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.
The next digit of our result is 4. 
Result so far: 12525.63157894
Subtracting 152 from 180 leaves us 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 12525.63157894 and a remainder of 2.8e-08.
