135236 ÷ 38 
The aim is to understand the frequency of 38 in 135236.

Step 1:
If we divide 1 by 38, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 38

Going ahead to step 2:
If we divide 13 by 38, we get 0 and a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 38

Step 3:
135 divided by 38 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 114 from 135 and we're left with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 38

On to step 4:
38 can be fit into 212 5 times, resulting in a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 35.0
Subtract 190 from 212 to get 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 38

Let's proceed to step 5:
The number 38 fits into 223 5 times, leaving a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 355.0
The remainder is 33 after subtracting 190 from 223.
Fetch the next digit (6) from the dividend, attach it to 33 and continue: 336 / 38

On to step 6:
The number 38 fits into 336 8 times, leaving a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 3558.0
If we take 304 away from 336, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
38 can be fit into 320 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 3558.8
Deduct 304 from 320 and we're left 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.

On to step 8:
When dividing 160 by 38, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3558.84
The remainder is 8 after subtracting 152 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
38 goes into 80 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 3558.842
If we take 76 away from 80, we end up 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 10:
If we divide 40 by 38, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 3558.8421
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.

Let's proceed to step 11:
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: 3558.8421
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 12:
38 goes into 200 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 3558.842105
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.

Let's proceed to step 13:
When dividing 100 by 38, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 3558.8421052
If we take 76 away from 100, we end up 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.

Let's proceed to step 14:
38 can be fit into 240 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 3558.84210526
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.

Our division results in 3558.84210526 with a remaining 1.2e-08.
