We look at the division of 575893 by 38 
The aim is to understand the frequency of 38 in 575893.

Let's proceed to step 1:
If we divide 5 by 38, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 38

Advancing to step 2:
The number 38 fits into 57 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 38 from 57 to get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 38

On to step 3:
If we divide 195 by 38, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 5 after subtracting 190 from 195.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 38

Let's proceed to step 4:
The number 38 fits into 58 1 times, leaving a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 151.0
If we take 38 away from 58, we end up with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 38

Advancing to step 5:
If we divide 209 by 38, we get 5 and a remainder of 19.
The next digit of our result is 5. 
Result so far: 1515.0
The remainder is 19 after subtracting 190 from 209.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 38

On to step 6:
193 divided by 38 is 5 with a remainder of 3.
Write down 5 as next digit of the result.

38 goes into 30 0 times with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 15155.0
If we take 0 away from 30, 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.

On to step 8:
If we divide 300 by 38, we get 7 and a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 15155.07
If we take 266 away from 300, we end up 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 9:
340 divided by 38 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 15155.078
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 10:
360 divided by 38 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 15155.0789
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.

Step 11:
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: 15155.07894
The remainder is 28 after subtracting 152 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
If we divide 280 by 38, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 15155.078947
Subtract 266 from 280 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
If we divide 140 by 38, we get 3 and a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 15155.0789473
If we take 114 away from 140, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 14:
38 goes into 260 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 15155.07894736
Deduct 228 from 260 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 15155.07894736 with a remaining 3.2e-08.
