We look at the division of 843786 by 38 
The aim is to understand the frequency of 38 in 843786.

Step 1:
38 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 38

Step 2:
If we divide 84 by 38, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 76 from 84, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 38

Advancing to step 3:
38 can be fit into 83 2 times, resulting in a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
The remainder is 7 after subtracting 76 from 83.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 38

Moving on to step 4:
The number 38 fits into 77 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 222.0
The remainder is 1 after subtracting 76 from 77.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 38

Step 5:
When dividing 18 by 38, we get 0 with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 2220.0
If we take 0 away from 18, we end up with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 38

Let's proceed to step 6:
The number 38 fits into 186 4 times, leaving a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 22204.0
Deduct 152 from 186 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
38 goes into 340 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 22204.8
Deduct 304 from 340 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
The number 38 fits into 360 9 times, leaving a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 22204.89
If we take 342 away from 360, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
38 can be fit into 180 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 22204.894
Subtract 152 from 180 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
38 goes into 280 7 times with a remainder of 14.
The next digit of our result is 7. 
Result so far: 22204.8947
Deduct 266 from 280 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
140 divided by 38 is 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 22204.89473
Subtracting 114 from 140 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
When dividing 260 by 38, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 22204.894736
Deduct 228 from 260 and we're left 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 13:
38 can be fit into 320 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 22204.8947368
If we subtract 304 from 320, we get 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 14:
160 divided by 38 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 22204.89473684
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.

Our division results in 22204.89473684 with a remaining 8e-09.
