We look at the division of 75605512 by 531 
The aim is to understand the frequency of 531 in 75605512.

Let's proceed to step 1:
When dividing 7 by 531, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 531

Going ahead to step 2:
531 goes into 75 0 times with a remainder of 75.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 75, we end up with 75.
Bring next digit (6) of the dividend behind the 75 and repeat the process: 756 / 531

On to step 3:
When dividing 756 by 531, we get 1 with a remainder of 225.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 531 from 756 leaves us with 225.
Bring next digit (0) of the dividend behind the 225 and repeat the process: 2250 / 531

Let's proceed to step 4:
2250 divided by 531 is 4 with a remainder of 126.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 126 after subtracting 2124 from 2250.
Include the next digit (5) from the dividend after 126, then repeat: 1265 / 531

On to step 5:
When dividing 1265 by 531, we get 2 with a remainder of 203.
The number 2 becomes the next digit in our result. 
Result so far: 142.0
If we subtract 1062 from 1265, we get 203.
Take the next digit (5) from the dividend and append it to 203, then repeat: 2035 / 531

Moving on to step 6:
When dividing 2035 by 531, we get 3 with a remainder of 442.
Record the quotient 3 as the next digit in the result. 
Result so far: 1423.0
Subtracting 1593 from 2035 leaves us with 442.
Include the next digit (1) from the dividend after 442, then repeat: 4421 / 531

Advancing to step 7:
If we divide 4421 by 531, we get 8 and a remainder of 173.
The number 8 becomes the next digit in our result. 
Result so far: 14238.0
Subtracting 4248 from 4421 leaves us with 173.
Take the next digit (2) from the dividend and append it to 173, then repeat: 1732 / 531

Let's proceed to step 8:
1732 divided by 531 is 3 with a remainder of 139.
The next digit of our result is 3. 
Result so far: 142383.0
If we take 1593 away from 1732, we end up with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Going ahead to step 9:
1390 divided by 531 is 2 with a remainder of 328.
Use 2 as the next digit of our solution. 
Result so far: 142383.2
Subtract 1062 from 1390 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Let's proceed to step 10:
3280 divided by 531 is 6 with a remainder of 94.
The next digit of our result is 6. 
Result so far: 142383.26
The remainder is 94 after subtracting 3186 from 3280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 11:
The number 531 fits into 940 1 times, leaving a remainder of 409.
The number 1 becomes the next digit in our result. 
Result so far: 142383.261
The remainder is 409 after subtracting 531 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Let's proceed to step 12:
When dividing 4090 by 531, we get 7 with a remainder of 373.
The next digit of our result is 7. 
Result so far: 142383.2617
Subtract 3717 from 4090 to get 373.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3730, and continue the process.

Moving on to step 13:
531 goes into 3730 7 times with a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 142383.26177
The remainder is 13 after subtracting 3717 from 3730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

In conclusion, the division gives 142383.26177 with a balance of 1.3e-05.
