We look at the division of 14900374 by 531 
The aim is to understand the frequency of 531 in 14900374.

Let's proceed to step 1:
531 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 531

Going ahead to step 2:
531 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 531

Advancing to step 3:
When dividing 149 by 531, we get 0 with a remainder of 149.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 149, we get 149.
Include the next digit (0) from the dividend after 149, then repeat: 1490 / 531

Let's proceed to step 4:
531 can be fit into 1490 2 times, resulting in a remainder of 428.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 428 after subtracting 1062 from 1490.
Bring next digit (0) of the dividend behind the 428 and repeat the process: 4280 / 531

On to step 5:
531 can be fit into 4280 8 times, resulting in a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Deduct 4248 from 4280 and we're left with 32.
Append the next digit (3) from the dividend to 32 and continue with: 323 / 531

Step 6:
When dividing 323 by 531, we get 0 with a remainder of 323.
Use 0 as the next digit of our solution. 
Result so far: 280.0
The remainder is 323 after subtracting 0 from 323.
Fetch the next digit (7) from the dividend, attach it to 323 and continue: 3237 / 531

Let's proceed to step 7:
If we divide 3237 by 531, we get 6 and a remainder of 51.
Use 6 as the next digit of our solution. 
Result so far: 2806.0
Deduct 3186 from 3237 and we're left with 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 531

Advancing to step 8:
If we divide 514 by 531, we get 0 and a remainder of 514.
Record the quotient 0 as the next digit in the result. 
Result so far: 28060.0
Deduct 0 from 514 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

On to step 9:
531 goes into 5140 9 times with a remainder of 361.
Put 9 as the next digit of the answer. 
Result so far: 28060.9
Subtracting 4779 from 5140 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 10:
531 goes into 3610 6 times with a remainder of 424.
The next digit of our result is 6. 
Result so far: 28060.96
The remainder is 424 after subtracting 3186 from 3610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 11:
If we divide 4240 by 531, we get 7 and a remainder of 523.
The next digit of our result is 7. 
Result so far: 28060.967
The remainder is 523 after subtracting 3717 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Moving on to step 12:
When dividing 5230 by 531, we get 9 with a remainder of 451.
The next digit of our result is 9. 
Result so far: 28060.9679
Deduct 4779 from 5230 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

On to step 13:
4510 divided by 531 is 8 with a remainder of 262.
Use 8 as the next digit of our solution. 
Result so far: 28060.96798
The remainder is 262 after subtracting 4248 from 4510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Let's proceed to step 14:
531 goes into 2620 4 times with a remainder of 496.
The number 4 becomes the next digit in our result. 
Result so far: 28060.967984
Subtract 2124 from 2620 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 15:
531 goes into 4960 9 times with a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 28060.9679849
Subtract 4779 from 4960 to get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Moving on to step 16:
531 goes into 1810 3 times with a remainder of 217.
Use 3 as the next digit of our solution. 
Result so far: 28060.96798493
If we subtract 1593 from 1810, we get 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

Our division results in 28060.96798493 with a remaining 2.17e-07.
