Let's divide 774574 by 86
The aim is to understand the frequency of 86 in 774574.

Let's proceed to step 1:
86 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 86

Moving on to step 2:
When dividing 77 by 86, we get 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 86

Advancing to step 3:
When dividing 774 by 86, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 774 from 774 and we're left with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 86

Step 4:
When dividing 5 by 86, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 90.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 86

Going ahead to step 5:
86 goes into 57 0 times with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 900.0
Subtracting 0 from 57 leaves us with 57.
Take the next digit (4) from the dividend and append it to 57, then repeat: 574 / 86

Step 6:
When dividing 574 by 86, we get 6 with a remainder of 58.
The next digit of our result is 6. 
Result so far: 9006.0
Subtract 516 from 574 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 7:
86 can be fit into 580 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 9006.6
Subtract 516 from 580 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
86 goes into 640 7 times with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 9006.67
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
The number 86 fits into 380 4 times, leaving a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 9006.674
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
The number 86 fits into 360 4 times, leaving a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 9006.6744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 9006.6744 with a remainder of 0.00016.
