677099 divided by 86 
The aim is to understand the frequency of 86 in 677099.

Moving on to step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 86

Step 2:
86 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Fetch the next digit (7) from the dividend, attach it to 67 and continue: 677 / 86

Step 3:
When dividing 677 by 86, we get 7 with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 602 from 677 leaves us with 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 86

Advancing to step 4:
If we divide 750 by 86, we get 8 and a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we subtract 688 from 750, we get 62.
Fetch the next digit (9) from the dividend, attach it to 62 and continue: 629 / 86

On to step 5:
The number 86 fits into 629 7 times, leaving a remainder of 27.
Put 7 as the next digit of the answer. 
Result so far: 787.0
Deduct 602 from 629 and we're left with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 86

Advancing to step 6:
If we divide 279 by 86, we get 3 and a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 7873.0
If we take 258 away from 279, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
The number 86 fits into 210 2 times, leaving a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 7873.2
If we subtract 172 from 210, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 8:
86 goes into 380 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 7873.24
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
When dividing 360 by 86, we get 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 7873.244
Deduct 344 from 360 and we're left with 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 outcome is 7873.244, with a leftover of 0.0016.
