452564 divided by 38 
The aim is to understand the frequency of 38 in 452564.

Let's proceed to step 1:
4 divided by 38 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 38

Advancing to step 2:
38 goes into 45 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 38 from 45 to get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 38

Let's proceed to step 3:
72 divided by 38 is 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 38 from 72 and we're left with 34.
Include the next digit (5) from the dividend after 34, then repeat: 345 / 38

On to step 4:
345 divided by 38 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 119.0
If we subtract 342 from 345, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 38

Step 5:
When dividing 36 by 38, we get 0 with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 1190.0
Subtract 0 from 36 to get 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 38

Moving on to step 6:
The number 38 fits into 364 9 times, leaving a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 11909.0
If we take 342 away from 364, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
38 can be fit into 220 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11909.5
Deduct 190 from 220 and we're left 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.

Step 8:
The number 38 fits into 300 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 11909.57
The remainder is 34 after subtracting 266 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
38 goes into 340 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 11909.578
If we take 304 away from 340, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 10:
38 goes into 360 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 11909.5789
The remainder is 18 after subtracting 342 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
38 can be fit into 180 4 times, resulting in a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 11909.57894
Subtract 152 from 180 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
38 can be fit into 280 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 11909.578947
If we take 266 away from 280, we end up with 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:
38 can be fit into 140 3 times, resulting in a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 11909.5789473
Subtract 114 from 140 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.

Advancing to step 14:
38 can be fit into 260 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 11909.57894736
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.

The final result is 11909.57894736 with a remainder of 3.2e-08.
