Let's divide 773984 by 86
The aim is to understand the frequency of 86 in 773984.

Step 1:
When dividing 7 by 86, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 86

On to step 2:
When dividing 77 by 86, we get 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Grab the next digit (3) from the dividend, add it to 77, then carry on: 773 / 86

Let's proceed to step 3:
86 goes into 773 8 times with a remainder of 85.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 688 from 773, we get 85.
Bring next digit (9) of the dividend behind the 85 and repeat the process: 859 / 86

Going ahead to step 4:
86 goes into 859 9 times with a remainder of 85.
Write down 9 as next digit of the result. 
Result so far: 89.0
Deduct 774 from 859 and we're left with 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 86

Moving on to step 5:
86 can be fit into 858 9 times, resulting in a remainder of 84.
Record the quotient 9 as the next digit in the result. 
Result so far: 899.0
If we subtract 774 from 858, we get 84.
Take the next digit (4) from the dividend and append it to 84, then repeat: 844 / 86

On to step 6:
The number 86 fits into 844 9 times, leaving a remainder of 70.
Write down 9 as next digit of the result. 
Result so far: 8999.0
Subtract 774 from 844 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 7:
When dividing 700 by 86, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 8999.8
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.

Going ahead to step 8:
The number 86 fits into 120 1 times, leaving a remainder of 34.
Write down 1 as next digit of the result. 
Result so far: 8999.81
If we subtract 86 from 120, we 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.

Moving on to step 9:
When dividing 340 by 86, we get 3 with a remainder of 82.
The next digit of our result is 3. 
Result so far: 8999.813
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.

On to step 10:
820 divided by 86 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 8999.8139
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
If we divide 460 by 86, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 8999.81395
If we subtract 430 from 460, we 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.

Going ahead to step 12:
300 divided by 86 is 3 with a remainder of 42.
The next digit of our result is 3. 
Result so far: 8999.813953
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 13:
86 goes into 420 4 times with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 8999.8139534
Subtracting 344 from 420 leaves us 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.

Going ahead to step 14:
760 divided by 86 is 8 with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 8999.81395348
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.

Our division results in 8999.81395348 with a remaining 7.2e-08.
