Let's divide 531090 by 85
The aim is to understand the frequency of 85 in 531090.

Moving on to step 1:
85 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 85

On to step 2:
If we divide 53 by 85, we get 0 and a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 85

On to step 3:
When dividing 531 by 85, we get 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 510 from 531 and we're left with 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 85

Let's proceed to step 4:
210 divided by 85 is 2 with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
If we take 170 away from 210, we end up with 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 85

On to step 5:
85 goes into 409 4 times with a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 624.0
Subtracting 340 from 409 leaves us with 69.
Take the next digit (0) from the dividend and append it to 69, then repeat: 690 / 85

Step 6:
The number 85 fits into 690 8 times, leaving a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 6248.0
The remainder is 10 after subtracting 680 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
85 can be fit into 100 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 6248.1
Subtracting 85 from 100 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
85 can be fit into 150 1 times, resulting in a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 6248.11
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

In conclusion, the division gives 6248.11 with a balance of 0.065.
