We divide 530451 by 86
The aim is to understand the frequency of 86 in 530451.

Step 1:
When dividing 5 by 86, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 86

Going ahead to step 2:
When dividing 53 by 86, we get 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Bring next digit (0) of the dividend behind the 53 and repeat the process: 530 / 86

Going ahead to step 3:
If we divide 530 by 86, we get 6 and a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 516 from 530 and we're left with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 86

Moving on to step 4:
86 goes into 144 1 times with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we take 86 away from 144, we end up with 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 86

Moving on to step 5:
The number 86 fits into 585 6 times, leaving a remainder of 69.
Use 6 as the next digit of our solution. 
Result so far: 616.0
The remainder is 69 after subtracting 516 from 585.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 86

Advancing to step 6:
86 can be fit into 691 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 6168.0
If we take 688 away from 691, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 86, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 6168.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 86 is 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 6168.03
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
The number 86 fits into 420 4 times, leaving a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 6168.034
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
When dividing 760 by 86, we get 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 6168.0348
Subtract 688 from 760 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 11:
86 can be fit into 720 8 times, resulting in a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 6168.03488
Subtracting 688 from 720 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

After the division, we end up with 6168.03488 and a remainder of 3.2e-05.
