We look at the division of 14351823 by 538 
The aim is to understand the frequency of 538 in 14351823.

Let's proceed to step 1:
The number 538 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 538

Moving on to step 2:
When dividing 14 by 538, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 538

On to step 3:
143 divided by 538 is 0 with a remainder of 143.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 143 after subtracting 0 from 143.
Take the next digit (5) from the dividend and append it to 143, then repeat: 1435 / 538

Advancing to step 4:
If we divide 1435 by 538, we get 2 and a remainder of 359.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1076 from 1435, we get 359.
Grab the next digit (1) from the dividend, add it to 359, then carry on: 3591 / 538

Moving on to step 5:
When dividing 3591 by 538, we get 6 with a remainder of 363.
The next digit of our result is 6. 
Result so far: 26.0
The remainder is 363 after subtracting 3228 from 3591.
Append the next digit (8) from the dividend to 363 and continue with: 3638 / 538

Step 6:
3638 divided by 538 is 6 with a remainder of 410.
Use 6 as the next digit of our solution. 
Result so far: 266.0
Subtract 3228 from 3638 to get 410.
Take the next digit (2) from the dividend and append it to 410, then repeat: 4102 / 538

Going ahead to step 7:
If we divide 4102 by 538, we get 7 and a remainder of 336.
The number 7 becomes the next digit in our result. 
Result so far: 2667.0
Subtracting 3766 from 4102 leaves us with 336.
Append the next digit (3) from the dividend to 336 and continue with: 3363 / 538

Let's proceed to step 8:
538 goes into 3363 6 times with a remainder of 135.
Put 6 as the next digit of the answer. 
Result so far: 26676.0
If we take 3228 away from 3363, we end up with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 9:
The number 538 fits into 1350 2 times, leaving a remainder of 274.
The next digit of our result is 2. 
Result so far: 26676.2
If we subtract 1076 from 1350, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Let's proceed to step 10:
538 goes into 2740 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 26676.25
If we subtract 2690 from 2740, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
If we divide 500 by 538, we get 0 and a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 26676.25
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 12:
5000 divided by 538 is 9 with a remainder of 158.
Use 9 as the next digit of our solution. 
Result so far: 26676.2509
Deduct 4842 from 5000 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 13:
When dividing 1580 by 538, we get 2 with a remainder of 504.
The number 2 becomes the next digit in our result. 
Result so far: 26676.25092
The remainder is 504 after subtracting 1076 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 14:
When dividing 5040 by 538, we get 9 with a remainder of 198.
Put 9 as the next digit of the answer. 
Result so far: 26676.250929
The remainder is 198 after subtracting 4842 from 5040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

On to step 15:
If we divide 1980 by 538, we get 3 and a remainder of 366.
The number 3 becomes the next digit in our result. 
Result so far: 26676.2509293
If we take 1614 away from 1980, we end up with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Let's proceed to step 16:
3660 divided by 538 is 6 with a remainder of 432.
Put 6 as the next digit of the answer. 
Result so far: 26676.25092936
Deduct 3228 from 3660 and we're left with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

The final outcome is 26676.25092936, with a leftover of 4.32e-07.
