We're dividing 652448 by 86 
The aim is to understand the frequency of 86 in 652448.

Advancing to step 1:
The number 86 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 86

Advancing to step 2:
86 goes into 65 0 times with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Fetch the next digit (2) from the dividend, attach it to 65 and continue: 652 / 86

Advancing to step 3:
86 can be fit into 652 7 times, resulting in a remainder of 50.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 602 from 652 leaves us with 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 86

Let's proceed to step 4:
86 can be fit into 504 5 times, resulting in a remainder of 74.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 430 from 504, we get 74.
Fetch the next digit (4) from the dividend, attach it to 74 and continue: 744 / 86

Going ahead to step 5:
When dividing 744 by 86, we get 8 with a remainder of 56.
The next digit of our result is 8. 
Result so far: 758.0
Deduct 688 from 744 and we're left with 56.
Include the next digit (8) from the dividend after 56, then repeat: 568 / 86

Going ahead to step 6:
When dividing 568 by 86, we get 6 with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 7586.0
Subtract 516 from 568 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 7:
When dividing 520 by 86, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 7586.6
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
86 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7586.6
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 86, we get 4 and a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 7586.604
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 10:
560 divided by 86 is 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 7586.6046
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 7586.60465
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
100 divided by 86 is 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 7586.604651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
When dividing 140 by 86, we get 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 7586.6046511
Deduct 86 from 140 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final outcome is 7586.6046511, with a leftover of 5.4e-07.
