We divide 15115240 by 537
The aim is to understand the frequency of 537 in 15115240.

Moving on to step 1:
The number 537 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 537

Moving on to step 2:
15 divided by 537 is 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Append the next digit (1) from the dividend to 15 and continue with: 151 / 537

Going ahead to step 3:
The number 537 fits into 151 0 times, leaving a remainder of 151.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 151, we get 151.
Take the next digit (1) from the dividend and append it to 151, then repeat: 1511 / 537

Advancing to step 4:
1511 divided by 537 is 2 with a remainder of 437.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1074 from 1511 and we're left with 437.
Include the next digit (5) from the dividend after 437, then repeat: 4375 / 537

Moving on to step 5:
The number 537 fits into 4375 8 times, leaving a remainder of 79.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 4296 from 4375, we get 79.
Bring next digit (2) of the dividend behind the 79 and repeat the process: 792 / 537

Going ahead to step 6:
When dividing 792 by 537, we get 1 with a remainder of 255.
The next digit of our result is 1. 
Result so far: 281.0
The remainder is 255 after subtracting 537 from 792.
Bring next digit (4) of the dividend behind the 255 and repeat the process: 2554 / 537

Step 7:
537 goes into 2554 4 times with a remainder of 406.
Record the quotient 4 as the next digit in the result. 
Result so far: 2814.0
The remainder is 406 after subtracting 2148 from 2554.
Append the next digit (0) from the dividend to 406 and continue with: 4060 / 537

Let's proceed to step 8:
When dividing 4060 by 537, we get 7 with a remainder of 301.
Record the quotient 7 as the next digit in the result. 
Result so far: 28147.0
If we take 3759 away from 4060, we end up with 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

Moving on to step 9:
The number 537 fits into 3010 5 times, leaving a remainder of 325.
Put 5 as the next digit of the answer. 
Result so far: 28147.5
The remainder is 325 after subtracting 2685 from 3010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 10:
537 can be fit into 3250 6 times, resulting in a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 28147.56
Subtract 3222 from 3250 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.

Let's proceed to step 11:
If we divide 280 by 537, we get 0 and a remainder of 280.
The next digit of our result is 0. 
Result so far: 28147.56
Subtracting 0 from 280 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
537 can be fit into 2800 5 times, resulting in a remainder of 115.
Record the quotient 5 as the next digit in the result. 
Result so far: 28147.5605
The remainder is 115 after subtracting 2685 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 13:
When dividing 1150 by 537, we get 2 with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 28147.56052
Deduct 1074 from 1150 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 14:
When dividing 760 by 537, we get 1 with a remainder of 223.
Use 1 as the next digit of our solution. 
Result so far: 28147.560521
Subtract 537 from 760 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 15:
If we divide 2230 by 537, we get 4 and a remainder of 82.
The number 4 becomes the next digit in our result. 
Result so far: 28147.5605214
If we take 2148 away from 2230, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 16:
The number 537 fits into 820 1 times, leaving a remainder of 283.
Put 1 as the next digit of the answer. 
Result so far: 28147.56052141
Subtract 537 from 820 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

The final result is 28147.56052141 with a remainder of 2.83e-07.
