We look at the division of 752408 by 38 
The aim is to understand the frequency of 38 in 752408.

Step 1:
38 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 38

On to step 2:
If we divide 75 by 38, we get 1 and a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 37 after subtracting 38 from 75.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 38

Moving on to step 3:
If we divide 372 by 38, we get 9 and a remainder of 30.
The next digit of our result is 9. 
Result so far: 19.0
If we take 342 away from 372, we end up with 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 38

Advancing to step 4:
38 goes into 304 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 198.0
If we take 304 away from 304, we end up with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 38

Moving on to step 5:
38 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1980.0
Subtract 0 from 0 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 38

Advancing to step 6:
38 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 19800.0
Subtract 0 from 8 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.

Step 7:
If we divide 80 by 38, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 19800.2
If we subtract 76 from 80, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 38, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 19800.21
Subtracting 38 from 40 leaves us 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.

Moving on to step 9:
38 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 19800.21
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
38 goes into 200 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 19800.2105
Deduct 190 from 200 and we're left 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:
100 divided by 38 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 19800.21052
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.

Moving on to step 12:
240 divided by 38 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 19800.210526
If we subtract 228 from 240, we get 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:
38 goes into 120 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 19800.2105263
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 14:
38 goes into 60 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 19800.21052631
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.

The final outcome is 19800.21052631, with a leftover of 2.2e-08.
