We look at the division of 564937 by 86 
The aim is to understand the frequency of 86 in 564937.

Advancing to step 1:
86 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 86

Let's proceed to step 2:
When dividing 56 by 86, we get 0 with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Take the next digit (4) from the dividend and append it to 56, then repeat: 564 / 86

Step 3:
If we divide 564 by 86, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 516 from 564, we get 48.
Take the next digit (9) from the dividend and append it to 48, then repeat: 489 / 86

Step 4:
The number 86 fits into 489 5 times, leaving a remainder of 59.
Use 5 as the next digit of our solution. 
Result so far: 65.0
If we take 430 away from 489, we end up with 59.
Grab the next digit (3) from the dividend, add it to 59, then carry on: 593 / 86

On to step 5:
86 can be fit into 593 6 times, resulting in a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 656.0
Subtract 516 from 593 to get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 86

Step 6:
86 goes into 777 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 6569.0
Deduct 774 from 777 and we're left 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.

Going ahead to step 7:
30 divided by 86 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 6569.0
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.

Advancing to step 8:
300 divided by 86 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 6569.03
If we take 258 away from 300, we end up 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.

Let's proceed to step 9:
When dividing 420 by 86, we get 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 6569.034
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 10:
When dividing 760 by 86, we get 8 with a remainder of 72.
The next digit of our result is 8. 
Result so far: 6569.0348
Deduct 688 from 760 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 6569.03488
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.

The final outcome is 6569.03488, with a leftover of 3.2e-05.
