We're dividing 573423 by 38 
The aim is to understand the frequency of 38 in 573423.

Step 1:
38 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 38

Let's proceed to step 2:
38 goes into 57 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 19 after subtracting 38 from 57.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 38

Moving on to step 3:
The number 38 fits into 193 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 190 away from 193, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 38

Advancing to step 4:
38 goes into 34 0 times with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 150.0
Subtracting 0 from 34 leaves us with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 38

Advancing to step 5:
The number 38 fits into 342 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 1509.0
Deduct 342 from 342 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 38

Going ahead to step 6:
If we divide 3 by 38, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 15090.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
38 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 15090.0
If we take 0 away from 30, we end up 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.

Going ahead to 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: 15090.07
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.

Let's proceed to step 9:
If we divide 340 by 38, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 15090.078
Deduct 304 from 340 and we're left 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.

Step 10:
If we divide 360 by 38, we get 9 and a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 15090.0789
Subtracting 342 from 360 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
180 divided by 38 is 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 15090.07894
If we subtract 152 from 180, we 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.

Advancing to step 12:
280 divided by 38 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 15090.078947
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.

Going ahead to step 13:
If we divide 140 by 38, we get 3 and a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 15090.0789473
The remainder is 26 after subtracting 114 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
If we divide 260 by 38, we get 6 and a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 15090.07894736
The remainder is 32 after subtracting 228 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 15090.07894736 with a remaining 3.2e-08.
