576423 ÷ 38 
The aim is to understand the frequency of 38 in 576423.

Let's proceed to step 1:
If we divide 5 by 38, we get 0 and 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.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 38

Step 2:
The number 38 fits into 57 1 times, leaving a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 38 from 57 leaves us with 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 38

Going ahead to step 3:
If we divide 196 by 38, we get 5 and a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 190 from 196, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 38

Step 4:
If we divide 64 by 38, we get 1 and a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
The remainder is 26 after subtracting 38 from 64.
Append the next digit (2) from the dividend to 26 and continue with: 262 / 38

Moving on to step 5:
38 goes into 262 6 times with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 1516.0
If we take 228 away from 262, we end up with 34.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 38

Step 6:
38 goes into 343 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 15169.0
Subtract 342 from 343 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
When dividing 10 by 38, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15169.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
38 goes into 100 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 15169.02
The remainder is 24 after subtracting 76 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
38 can be fit into 240 6 times, resulting in a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 15169.026
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 10:
The number 38 fits into 120 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 15169.0263
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.

On to step 11:
38 goes into 60 1 times with a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 15169.02631
The remainder is 22 after subtracting 38 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
38 goes into 220 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 15169.026315
Subtract 190 from 220 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 13:
38 goes into 300 7 times with a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 15169.0263157
Subtracting 266 from 300 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 14:
38 goes into 340 8 times with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 15169.02631578
Subtracting 304 from 340 leaves us 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.

The quotient of the division is 15169.02631578, and the remainder is 3.6e-08.
