We look at the division of 13068773 by 538 
The aim is to understand the frequency of 538 in 13068773.

Let's proceed to step 1:
If we divide 1 by 538, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 538

Moving on to step 2:
538 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 538

Going ahead to step 3:
130 divided by 538 is 0 with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 130 leaves us with 130.
Bring next digit (6) of the dividend behind the 130 and repeat the process: 1306 / 538

Let's proceed to step 4:
538 can be fit into 1306 2 times, resulting in a remainder of 230.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 230 after subtracting 1076 from 1306.
Take the next digit (8) from the dividend and append it to 230, then repeat: 2308 / 538

On to step 5:
2308 divided by 538 is 4 with a remainder of 156.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we subtract 2152 from 2308, we get 156.
Bring next digit (7) of the dividend behind the 156 and repeat the process: 1567 / 538

On to step 6:
538 goes into 1567 2 times with a remainder of 491.
Put 2 as the next digit of the answer. 
Result so far: 242.0
The remainder is 491 after subtracting 1076 from 1567.
Include the next digit (7) from the dividend after 491, then repeat: 4917 / 538

Going ahead to step 7:
If we divide 4917 by 538, we get 9 and a remainder of 75.
Write down 9 as next digit of the result. 
Result so far: 2429.0
Subtracting 4842 from 4917 leaves us with 75.
Bring next digit (3) of the dividend behind the 75 and repeat the process: 753 / 538

Step 8:
If we divide 753 by 538, we get 1 and a remainder of 215.
Write down 1 as next digit of the result. 
Result so far: 24291.0
Deduct 538 from 753 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Advancing to step 9:
538 goes into 2150 3 times with a remainder of 536.
Record the quotient 3 as the next digit in the result. 
Result so far: 24291.3
Subtracting 1614 from 2150 leaves us with 536.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Going ahead to step 10:
538 goes into 5360 9 times with a remainder of 518.
Write down 9 as next digit of the result. 
Result so far: 24291.39
The remainder is 518 after subtracting 4842 from 5360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5180, and continue the process.

Moving on to step 11:
5180 divided by 538 is 9 with a remainder of 338.
The next digit of our result is 9. 
Result so far: 24291.399
Deduct 4842 from 5180 and we're left with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

After the division, we end up with 24291.399 and a remainder of 0.0338.
