We look at the division of 578919 by 38 
The aim is to understand the frequency of 38 in 578919.

Step 1:
38 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 38

Going ahead to step 2:
If we divide 57 by 38, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 19 after subtracting 38 from 57.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 38

Step 3:
If we divide 198 by 38, we get 5 and a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 8 after subtracting 190 from 198.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 38

Going ahead to step 4:
89 divided by 38 is 2 with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 152.0
If we take 76 away from 89, we end up with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 38

Let's proceed to step 5:
When dividing 131 by 38, we get 3 with a remainder of 17.
Record the quotient 3 as the next digit in the result. 
Result so far: 1523.0
If we take 114 away from 131, we end up with 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 38

Moving on to step 6:
The number 38 fits into 179 4 times, leaving a remainder of 27.
Use 4 as the next digit of our solution. 
Result so far: 15234.0
If we subtract 152 from 179, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 7:
When dividing 270 by 38, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 15234.7
The remainder is 4 after subtracting 266 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 38 fits into 40 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 15234.71
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
If we divide 20 by 38, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15234.71
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
The number 38 fits into 200 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15234.7105
If we take 190 away from 200, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
If we divide 100 by 38, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 15234.71052
If we take 76 away from 100, 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.

Going ahead to step 12:
240 divided by 38 is 6 with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 15234.710526
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.

On to step 13:
120 divided by 38 is 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 15234.7105263
Subtract 114 from 120 to 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 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: 15234.71052631
If we subtract 38 from 60, we 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.

In conclusion, the division gives 15234.71052631 with a balance of 2.2e-08.
