408792 ÷ 38 
The aim is to understand the frequency of 38 in 408792.

On to step 1:
If we divide 4 by 38, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 38

Moving on to step 2:
If we divide 40 by 38, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 38 from 40 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 38

Step 3:
The number 38 fits into 28 0 times, leaving a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 38

On to step 4:
287 divided by 38 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Deduct 266 from 287 and we're left with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 38

Step 5:
If we divide 219 by 38, we get 5 and a remainder of 29.
The next digit of our result is 5. 
Result so far: 1075.0
Subtracting 190 from 219 leaves us with 29.
Include the next digit (2) from the dividend after 29, then repeat: 292 / 38

Let's proceed to step 6:
38 can be fit into 292 7 times, resulting in a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 10757.0
Subtract 266 from 292 to get 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 7:
The number 38 fits into 260 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 10757.6
Subtract 228 from 260 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 8:
320 divided by 38 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 10757.68
The remainder is 16 after subtracting 304 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
When dividing 160 by 38, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 10757.684
Subtract 152 from 160 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
When dividing 80 by 38, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 10757.6842
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 11:
When dividing 40 by 38, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 10757.68421
Deduct 38 from 40 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
20 divided by 38 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 10757.68421
Deduct 0 from 20 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 13:
If we divide 200 by 38, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 10757.6842105
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.

Step 14:
38 can be fit into 100 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 10757.68421052
If we subtract 76 from 100, 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.

The final result is 10757.68421052 with a remainder of 2.4e-08.
