We're dividing 71917 by 38 
The aim is to understand the frequency of 38 in 71917.

Step 1:
7 divided by 38 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 38

Moving on to step 2:
If we divide 71 by 38, we get 1 and a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 38 from 71, we get 33.
Grab the next digit (9) from the dividend, add it to 33, then carry on: 339 / 38

Step 3:
38 goes into 339 8 times with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 304 away from 339, we end up with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 38

Let's proceed to step 4:
When dividing 351 by 38, we get 9 with a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 189.0
The remainder is 9 after subtracting 342 from 351.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 38

Moving on to step 5:
If we divide 97 by 38, we get 2 and a remainder of 21.
The next digit of our result is 2. 
Result so far: 1892.0
Subtracting 76 from 97 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 6:
38 can be fit into 210 5 times, resulting in a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 1892.5
Deduct 190 from 210 and we're left 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.

Going ahead to step 7:
If we divide 200 by 38, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 1892.55
The remainder is 10 after subtracting 190 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 1892.55, with a leftover of 0.01.
