574302 ÷ 38 
The aim is to understand the frequency of 38 in 574302.

On to step 1:
38 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 38

On to step 2:
If we divide 57 by 38, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 38 from 57 and we're left with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 38

Going ahead to step 3:
The number 38 fits into 194 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 190 from 194 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 38

Step 4:
The number 38 fits into 43 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
If we take 38 away from 43, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 38

Let's proceed to step 5:
When dividing 50 by 38, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1511.0
Subtract 38 from 50 to get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 38

Advancing to step 6:
38 can be fit into 122 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 15113.0
If we subtract 114 from 122, we 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:
When dividing 80 by 38, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 15113.2
Subtract 76 from 80 to 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.

On to step 8:
The number 38 fits into 40 1 times, leaving a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 15113.21
If we take 38 away from 40, we end up 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 9:
38 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 15113.21
Subtracting 0 from 20 leaves us 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.

Moving on to step 10:
The number 38 fits into 200 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 15113.2105
Subtracting 190 from 200 leaves us 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.

Moving on to step 11:
If we divide 100 by 38, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 15113.21052
Subtract 76 from 100 to 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.

Going ahead to step 12:
The number 38 fits into 240 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 15113.210526
Subtracting 228 from 240 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
When dividing 120 by 38, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 15113.2105263
Subtracting 114 from 120 leaves us 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.

On to step 14:
60 divided by 38 is 1 with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 15113.21052631
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.

After the division, we end up with 15113.21052631 and a remainder of 2.2e-08.
