We look at the division of 772052 by 86 
The aim is to understand the frequency of 86 in 772052.

Step 1:
7 divided by 86 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 86

Going ahead to step 2:
86 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Grab the next digit (2) from the dividend, add it to 77, then carry on: 772 / 86

On to step 3:
The number 86 fits into 772 8 times, leaving a remainder of 84.
The next digit of our result is 8. 
Result so far: 8.0
If we take 688 away from 772, we end up with 84.
Bring next digit (0) of the dividend behind the 84 and repeat the process: 840 / 86

Going ahead to step 4:
When dividing 840 by 86, we get 9 with a remainder of 66.
The next digit of our result is 9. 
Result so far: 89.0
Subtracting 774 from 840 leaves us with 66.
Include the next digit (5) from the dividend after 66, then repeat: 665 / 86

On to step 5:
86 can be fit into 665 7 times, resulting in a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 897.0
Subtracting 602 from 665 leaves us with 63.
Grab the next digit (2) from the dividend, add it to 63, then carry on: 632 / 86

On to step 6:
86 goes into 632 7 times with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 8977.0
Subtract 602 from 632 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 7:
When dividing 300 by 86, we get 3 with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 8977.3
Subtract 258 from 300 to get 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 8:
When dividing 420 by 86, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 8977.34
If we subtract 344 from 420, we 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 9:
760 divided by 86 is 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 8977.348
If we subtract 688 from 760, we 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.

Advancing to step 10:
When dividing 720 by 86, we get 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 8977.3488
Subtract 688 from 720 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 8977.3488 with a remaining 0.00032.
