493913 ÷ 38 
The aim is to understand the frequency of 38 in 493913.

Let's proceed to step 1:
When dividing 4 by 38, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 38

Moving on to step 2:
49 divided by 38 is 1 with a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 38 from 49 and we're left with 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 38

Advancing to step 3:
If we divide 113 by 38, we get 2 and a remainder of 37.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 76 from 113 and we're left with 37.
Bring next digit (9) of the dividend behind the 37 and repeat the process: 379 / 38

On to step 4:
When dividing 379 by 38, we get 9 with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
The remainder is 37 after subtracting 342 from 379.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 38

Going ahead to step 5:
371 divided by 38 is 9 with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 1299.0
If we take 342 away from 371, we end up with 29.
Grab the next digit (3) from the dividend, add it to 29, then carry on: 293 / 38

Let's proceed to step 6:
The number 38 fits into 293 7 times, leaving a remainder of 27.
The next digit of our result is 7. 
Result so far: 12997.0
Subtracting 266 from 293 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
The number 38 fits into 270 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 12997.7
Subtracting 266 from 270 leaves us 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.

Going ahead to step 8:
38 can be fit into 40 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 12997.71
The remainder is 2 after subtracting 38 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
If we divide 20 by 38, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12997.71
Subtract 0 from 20 to get 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:
200 divided by 38 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 12997.7105
The remainder is 10 after subtracting 190 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
38 goes into 100 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 12997.71052
The remainder is 24 after subtracting 76 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
38 goes into 240 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 12997.710526
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:
The number 38 fits into 120 3 times, leaving a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 12997.7105263
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.

Let's proceed to step 14:
60 divided by 38 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 12997.71052631
Subtracting 38 from 60 leaves us 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.

Our division results in 12997.71052631 with a remaining 2.2e-08.
