We look at the division of 428576 by 38 
The aim is to understand the frequency of 38 in 428576.

Let's proceed to step 1:
4 divided by 38 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 38

On to step 2:
The number 38 fits into 42 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 4 after subtracting 38 from 42.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 38

Step 3:
38 goes into 48 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 11.0
If we take 38 away from 48, we end up with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 38

Advancing to step 4:
38 goes into 105 2 times with a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 112.0
Subtracting 76 from 105 leaves us with 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 38

Let's proceed to step 5:
When dividing 297 by 38, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 1127.0
Subtracting 266 from 297 leaves us with 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 38

Moving on to step 6:
38 can be fit into 316 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 11278.0
Subtract 304 from 316 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
The number 38 fits into 120 3 times, leaving a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 11278.3
The remainder is 6 after subtracting 114 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
38 goes into 60 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 11278.31
If we take 38 away from 60, 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.

Going ahead to step 9:
220 divided by 38 is 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 11278.315
The remainder is 30 after subtracting 190 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
38 can be fit into 300 7 times, resulting in a remainder of 34.
The next digit of our result is 7. 
Result so far: 11278.3157
If we subtract 266 from 300, we get 34.
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 11:
If we divide 340 by 38, we get 8 and a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 11278.31578
The remainder is 36 after subtracting 304 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
360 divided by 38 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 11278.315789
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.

Going ahead to step 13:
38 goes into 180 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 11278.3157894
If we take 152 away from 180, we end up with 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 14:
If we divide 280 by 38, we get 7 and a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 11278.31578947
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.

The final result is 11278.31578947 with a remainder of 1.4e-08.
