We look at the division of 89958749 by 531 
The aim is to understand the frequency of 531 in 89958749.

Advancing to step 1:
The number 531 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 531

On to step 2:
89 divided by 531 is 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Append the next digit (9) from the dividend to 89 and continue with: 899 / 531

Going ahead to step 3:
531 can be fit into 899 1 times, resulting in a remainder of 368.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 368 after subtracting 531 from 899.
Grab the next digit (5) from the dividend, add it to 368, then carry on: 3685 / 531

Step 4:
The number 531 fits into 3685 6 times, leaving a remainder of 499.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 3186 from 3685 leaves us with 499.
Include the next digit (8) from the dividend after 499, then repeat: 4998 / 531

Step 5:
531 goes into 4998 9 times with a remainder of 219.
Use 9 as the next digit of our solution. 
Result so far: 169.0
If we subtract 4779 from 4998, we get 219.
Include the next digit (7) from the dividend after 219, then repeat: 2197 / 531

On to step 6:
2197 divided by 531 is 4 with a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 1694.0
Subtracting 2124 from 2197 leaves us with 73.
Bring next digit (4) of the dividend behind the 73 and repeat the process: 734 / 531

Step 7:
734 divided by 531 is 1 with a remainder of 203.
Put 1 as the next digit of the answer. 
Result so far: 16941.0
If we take 531 away from 734, we end up with 203.
Grab the next digit (9) from the dividend, add it to 203, then carry on: 2039 / 531

Let's proceed to step 8:
531 can be fit into 2039 3 times, resulting in a remainder of 446.
The number 3 becomes the next digit in our result. 
Result so far: 169413.0
If we take 1593 away from 2039, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

On to step 9:
4460 divided by 531 is 8 with a remainder of 212.
Use 8 as the next digit of our solution. 
Result so far: 169413.8
Subtracting 4248 from 4460 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Let's proceed to step 10:
When dividing 2120 by 531, we get 3 with a remainder of 527.
Record the quotient 3 as the next digit in the result. 
Result so far: 169413.83
If we subtract 1593 from 2120, we get 527.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5270, and continue the process.

Let's proceed to step 11:
If we divide 5270 by 531, we get 9 and a remainder of 491.
The next digit of our result is 9. 
Result so far: 169413.839
Deduct 4779 from 5270 and we're left with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

Step 12:
531 can be fit into 4910 9 times, resulting in a remainder of 131.
Record the quotient 9 as the next digit in the result. 
Result so far: 169413.8399
The remainder is 131 after subtracting 4779 from 4910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

The quotient of the division is 169413.8399, and the remainder is 0.00131.
