We look at the division of 491633 by 38 
The aim is to understand the frequency of 38 in 491633.

Advancing 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
Deduct 0 from 4 and we're left with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 38

Moving on to step 2:
38 goes into 49 1 times with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 38 from 49 and we're left with 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 38

On to step 3:
38 goes into 111 2 times with a remainder of 35.
Write down 2 as next digit of the result. 
Result so far: 12.0
The remainder is 35 after subtracting 76 from 111.
Grab the next digit (6) from the dividend, add it to 35, then carry on: 356 / 38

Going ahead to step 4:
356 divided by 38 is 9 with a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 129.0
Deduct 342 from 356 and we're left with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 38

Moving on to step 5:
When dividing 143 by 38, we get 3 with a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 1293.0
Subtracting 114 from 143 leaves us with 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 38

Going ahead to step 6:
If we divide 293 by 38, we get 7 and a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 12937.0
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.

Going ahead to step 7:
When dividing 270 by 38, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 12937.7
The remainder is 4 after subtracting 266 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
The number 38 fits into 40 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 12937.71
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.

Let's proceed to step 9:
The number 38 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 12937.71
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
38 can be fit into 200 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 12937.7105
Subtracting 190 from 200 leaves us with 10.
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.
Record the quotient 2 as the next digit in the result. 
Result so far: 12937.71052
Subtracting 76 from 100 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 12:
240 divided by 38 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 12937.710526
Deduct 228 from 240 and we're left 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.

Going ahead to step 13:
38 goes into 120 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 12937.7105263
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:
If we divide 60 by 38, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 12937.71052631
Subtract 38 from 60 to 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.

In conclusion, the division gives 12937.71052631 with a balance of 2.2e-08.
