We look at the division of 14515613 by 537 
The aim is to understand the frequency of 537 in 14515613.

Advancing to step 1:
537 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
If we take 0 away from 1, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 537

Step 2:
537 can be fit into 14 0 times, resulting in a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 537

Let's proceed to step 3:
537 goes into 145 0 times with a remainder of 145.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 145 to get 145.
Fetch the next digit (1) from the dividend, attach it to 145 and continue: 1451 / 537

Let's proceed to step 4:
1451 divided by 537 is 2 with a remainder of 377.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 377 after subtracting 1074 from 1451.
Include the next digit (5) from the dividend after 377, then repeat: 3775 / 537

Going ahead to step 5:
537 can be fit into 3775 7 times, resulting in a remainder of 16.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 3759 from 3775 leaves us with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 537

Let's proceed to step 6:
The number 537 fits into 166 0 times, leaving a remainder of 166.
Put 0 as the next digit of the answer. 
Result so far: 270.0
Subtracting 0 from 166 leaves us with 166.
Bring next digit (1) of the dividend behind the 166 and repeat the process: 1661 / 537

Step 7:
1661 divided by 537 is 3 with a remainder of 50.
Record the quotient 3 as the next digit in the result. 
Result so far: 2703.0
If we take 1611 away from 1661, we end up with 50.
Take the next digit (3) from the dividend and append it to 50, then repeat: 503 / 537

On to step 8:
503 divided by 537 is 0 with a remainder of 503.
Put 0 as the next digit of the answer. 
Result so far: 27030.0
If we take 0 away from 503, we end up with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

Moving on to step 9:
5030 divided by 537 is 9 with a remainder of 197.
Use 9 as the next digit of our solution. 
Result so far: 27030.9
Subtract 4833 from 5030 to get 197.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

Moving on to step 10:
1970 divided by 537 is 3 with a remainder of 359.
Write down 3 as next digit of the result. 
Result so far: 27030.93
If we subtract 1611 from 1970, we get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Let's proceed to step 11:
537 goes into 3590 6 times with a remainder of 368.
The next digit of our result is 6. 
Result so far: 27030.936
Deduct 3222 from 3590 and we're left with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Moving on to step 12:
The number 537 fits into 3680 6 times, leaving a remainder of 458.
Put 6 as the next digit of the answer. 
Result so far: 27030.9366
Subtract 3222 from 3680 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

After the division, we end up with 27030.9366 and a remainder of 0.00458.
