We're dividing 131816 by 38 
The aim is to understand the frequency of 38 in 131816.

Let's proceed to step 1:
38 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 38

On to step 2:
38 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (1) from the dividend after 13, then repeat: 131 / 38

Advancing to step 3:
If we divide 131 by 38, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 114 from 131 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 38

On to step 4:
178 divided by 38 is 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 152 from 178, we get 26.
Take the next digit (1) from the dividend and append it to 26, then repeat: 261 / 38

Going ahead to step 5:
38 can be fit into 261 6 times, resulting in a remainder of 33.
The next digit of our result is 6. 
Result so far: 346.0
Deduct 228 from 261 and we're left with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 38

Advancing to step 6:
336 divided by 38 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 3468.0
The remainder is 32 after subtracting 304 from 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
The number 38 fits into 320 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 3468.8
Subtracting 304 from 320 leaves us 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.

Going ahead to step 8:
If we divide 160 by 38, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 3468.84
Subtracting 152 from 160 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
38 goes into 80 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 3468.842
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 10:
The number 38 fits into 40 1 times, leaving a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 3468.8421
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.

Step 11:
The number 38 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 3468.8421
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.

Going ahead to step 12:
200 divided by 38 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 3468.842105
Deduct 190 from 200 and we're left 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.

Going ahead to step 13:
38 can be fit into 100 2 times, resulting in a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 3468.8421052
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.

Advancing to step 14:
38 goes into 240 6 times with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 3468.84210526
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.

The final outcome is 3468.84210526, with a leftover of 1.2e-08.
