504439 divided by 38 
The aim is to understand the frequency of 38 in 504439.

Going ahead to step 1:
If we divide 5 by 38, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 38

Step 2:
The number 38 fits into 50 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 38 from 50, we get 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 38

Let's proceed to step 3:
The number 38 fits into 124 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 114 from 124 to get 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 38

Advancing to step 4:
38 goes into 104 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
If we subtract 76 from 104, we get 28.
Grab the next digit (3) from the dividend, add it to 28, then carry on: 283 / 38

Let's proceed to step 5:
38 goes into 283 7 times with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 1327.0
If we take 266 away from 283, we end up with 17.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 38

Let's proceed to step 6:
179 divided by 38 is 4 with a remainder of 27.
Record the quotient 4 as the next digit in the result. 
Result so far: 13274.0
If we subtract 152 from 179, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
38 goes into 270 7 times with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 13274.7
Deduct 266 from 270 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
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: 13274.71
Subtracting 38 from 40 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
20 divided by 38 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 13274.71
If we take 0 away from 20, we end up 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.

Advancing to step 10:
38 goes into 200 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 13274.7105
Subtract 190 from 200 to 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 11:
When dividing 100 by 38, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 13274.71052
If we subtract 76 from 100, we get 24.
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 12:
If we divide 240 by 38, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 13274.710526
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.

Advancing to step 13:
38 can be fit into 120 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 13274.7105263
Subtract 114 from 120 to get 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 14:
38 can be fit into 60 1 times, resulting in a remainder of 22.
The next digit of our result is 1. 
Result so far: 13274.71052631
If we subtract 38 from 60, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final outcome is 13274.71052631, with a leftover of 2.2e-08.
