Let's divide 604608 by 38
The aim is to understand the frequency of 38 in 604608.

On to step 1:
If we divide 6 by 38, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 38

Moving on to step 2:
The number 38 fits into 60 1 times, leaving a remainder of 22.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 22 after subtracting 38 from 60.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 38

On to step 3:
38 goes into 224 5 times with a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 190 from 224, we get 34.
Grab the next digit (6) from the dividend, add it to 34, then carry on: 346 / 38

Step 4:
38 goes into 346 9 times with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
Subtracting 342 from 346 leaves us with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 38

Going ahead to step 5:
If we divide 40 by 38, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 1591.0
Subtract 38 from 40 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 38

Moving on to step 6:
38 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 15910.0
If we subtract 0 from 28, 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 7:
If we divide 280 by 38, we get 7 and a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 15910.7
Deduct 266 from 280 and we're left 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.

Let's proceed to step 8:
The number 38 fits into 140 3 times, leaving a remainder of 26.
The next digit of our result is 3. 
Result so far: 15910.73
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.

On to step 9:
38 can be fit into 260 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 15910.736
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.

Going ahead to step 10:
The number 38 fits into 320 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 15910.7368
If we take 304 away from 320, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
The number 38 fits into 160 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 15910.73684
If we subtract 152 from 160, 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.

Moving on to step 12:
38 goes into 80 2 times with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 15910.736842
The remainder is 4 after subtracting 76 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
If we divide 40 by 38, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 15910.7368421
Subtract 38 from 40 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
The number 38 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 15910.7368421
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.

The final outcome is 15910.7368421, with a leftover of 2e-08.
