We look at the division of 57144 by 38 
The aim is to understand the frequency of 38 in 57144.

On to step 1:
If we divide 5 by 38, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 38

Going ahead to step 2:
38 can be fit into 57 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 38 from 57 and we're left with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 38

Going ahead to step 3:
The number 38 fits into 191 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtract 190 from 191 to get 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 38

Going ahead to step 4:
If we divide 14 by 38, we get 0 and a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Deduct 0 from 14 and we're left with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 38

On to step 5:
38 goes into 144 3 times with a remainder of 30.
The next digit of our result is 3. 
Result so far: 1503.0
If we subtract 114 from 144, we 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.

Going ahead to step 6:
38 can be fit into 300 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 1503.7
If we take 266 away from 300, we end up 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 7:
340 divided by 38 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 1503.78
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.

Moving on to step 8:
38 can be fit into 360 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 1503.789
Subtract 342 from 360 to get 18.
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 9:
38 can be fit into 180 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 1503.7894
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.

On to step 10:
280 divided by 38 is 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 1503.78947
The remainder is 14 after subtracting 266 from 280.
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 11:
140 divided by 38 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 1503.789473
If we take 114 away from 140, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 12:
When dividing 260 by 38, we get 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 1503.7894736
If we subtract 228 from 260, we 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.

On to step 13:
The number 38 fits into 320 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 1503.78947368
The remainder is 16 after subtracting 304 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 1503.78947368 with a balance of 1.6e-08.
