We look at the division of 744748 by 38 
The aim is to understand the frequency of 38 in 744748.

Advancing to step 1:
If we divide 7 by 38, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 38

Advancing to step 2:
If we divide 74 by 38, we get 1 and a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 38 from 74, we get 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 38

Going ahead to step 3:
38 goes into 364 9 times with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 342 from 364 and we're left with 22.
Bring next digit (7) of the dividend behind the 22 and repeat the process: 227 / 38

Moving on to step 4:
227 divided by 38 is 5 with a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 195.0
Subtract 190 from 227 to get 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 38

Going ahead to step 5:
The number 38 fits into 374 9 times, leaving a remainder of 32.
The number 9 becomes the next digit in our result. 
Result so far: 1959.0
If we subtract 342 from 374, we get 32.
Take the next digit (8) from the dividend and append it to 32, then repeat: 328 / 38

Going ahead to step 6:
If we divide 328 by 38, we get 8 and a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 19598.0
If we take 304 away from 328, 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.

Moving on to step 7:
If we divide 240 by 38, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 19598.6
If we take 228 away from 240, we end up with 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:
When dividing 120 by 38, we get 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 19598.63
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.

Moving on to step 9:
38 goes into 60 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 19598.631
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.

On to step 10:
38 can be fit into 220 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 19598.6315
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.

Step 11:
When dividing 300 by 38, we get 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 19598.63157
If we subtract 266 from 300, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 38 fits into 340 8 times, leaving a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 19598.631578
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.

Let's proceed to step 13:
38 goes into 360 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 19598.6315789
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.

Let's proceed to step 14:
When dividing 180 by 38, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 19598.63157894
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.

The final result is 19598.63157894 with a remainder of 2.8e-08.
