We look at the division of 23819354 by 531 
The aim is to understand the frequency of 531 in 23819354.

Step 1:
The number 531 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 531

Step 2:
The number 531 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 531

Let's proceed to step 3:
When dividing 238 by 531, we get 0 with a remainder of 238.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 238 after subtracting 0 from 238.
Append the next digit (1) from the dividend to 238 and continue with: 2381 / 531

On to step 4:
2381 divided by 531 is 4 with a remainder of 257.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2124 from 2381 to get 257.
Bring next digit (9) of the dividend behind the 257 and repeat the process: 2579 / 531

Moving on to step 5:
531 goes into 2579 4 times with a remainder of 455.
Write down 4 as next digit of the result. 
Result so far: 44.0
Subtracting 2124 from 2579 leaves us with 455.
Append the next digit (3) from the dividend to 455 and continue with: 4553 / 531

Advancing to step 6:
531 can be fit into 4553 8 times, resulting in a remainder of 305.
Put 8 as the next digit of the answer. 
Result so far: 448.0
If we take 4248 away from 4553, we end up with 305.
Grab the next digit (5) from the dividend, add it to 305, then carry on: 3055 / 531

Let's proceed to step 7:
3055 divided by 531 is 5 with a remainder of 400.
Use 5 as the next digit of our solution. 
Result so far: 4485.0
Deduct 2655 from 3055 and we're left with 400.
Include the next digit (4) from the dividend after 400, then repeat: 4004 / 531

Moving on to step 8:
If we divide 4004 by 531, we get 7 and a remainder of 287.
Put 7 as the next digit of the answer. 
Result so far: 44857.0
If we take 3717 away from 4004, we end up with 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

On to step 9:
When dividing 2870 by 531, we get 5 with a remainder of 215.
Write down 5 as next digit of the result. 
Result so far: 44857.5
The remainder is 215 after subtracting 2655 from 2870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Let's proceed to step 10:
2150 divided by 531 is 4 with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 44857.54
The remainder is 26 after subtracting 2124 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
531 can be fit into 260 0 times, resulting in a remainder of 260.
Use 0 as the next digit of our solution. 
Result so far: 44857.54
Deduct 0 from 260 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Going ahead to step 12:
2600 divided by 531 is 4 with a remainder of 476.
The number 4 becomes the next digit in our result. 
Result so far: 44857.5404
The remainder is 476 after subtracting 2124 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 13:
531 can be fit into 4760 8 times, resulting in a remainder of 512.
The number 8 becomes the next digit in our result. 
Result so far: 44857.54048
Subtract 4248 from 4760 to get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Moving on to step 14:
The number 531 fits into 5120 9 times, leaving a remainder of 341.
The number 9 becomes the next digit in our result. 
Result so far: 44857.540489
The remainder is 341 after subtracting 4779 from 5120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3410, and continue the process.

Going ahead to step 15:
3410 divided by 531 is 6 with a remainder of 224.
Record the quotient 6 as the next digit in the result. 
Result so far: 44857.5404896
The remainder is 224 after subtracting 3186 from 3410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 16:
If we divide 2240 by 531, we get 4 and a remainder of 116.
The next digit of our result is 4. 
Result so far: 44857.54048964
Subtracting 2124 from 2240 leaves us with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

After the division, we end up with 44857.54048964 and a remainder of 1.16e-07.
