We look at the division of 774222 by 86 
The aim is to understand the frequency of 86 in 774222.

Going ahead to step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 86

Moving on to step 2:
When dividing 77 by 86, we get 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Include the next digit (4) from the dividend after 77, then repeat: 774 / 86

Moving on to step 3:
When dividing 774 by 86, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 774 from 774 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 86

Let's proceed to step 4:
86 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 90.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 86

Step 5:
The number 86 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 900.0
Deduct 0 from 22 and we're left with 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 86

Going ahead to step 6:
The number 86 fits into 222 2 times, leaving a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 9002.0
Subtract 172 from 222 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 7:
500 divided by 86 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 9002.5
Deduct 430 from 500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
When dividing 700 by 86, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 9002.58
The remainder is 12 after subtracting 688 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 86, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 9002.581
Subtract 86 from 120 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 10:
86 goes into 340 3 times with a remainder of 82.
The next digit of our result is 3. 
Result so far: 9002.5813
Subtract 258 from 340 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 11:
The number 86 fits into 820 9 times, leaving a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 9002.58139
Subtract 774 from 820 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 12:
When dividing 460 by 86, we get 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 9002.581395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
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: 9002.5813953
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.

Moving on to step 14:
86 can be fit into 420 4 times, resulting in a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 9002.58139534
If we take 344 away from 420, we end up 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.

The quotient of the division is 9002.58139534, and the remainder is 7.6e-08.
