678263 divided by 86 
The aim is to understand the frequency of 86 in 678263.

Advancing to step 1:
86 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 86

On to step 2:
The number 86 fits into 67 0 times, leaving a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Append the next digit (8) from the dividend to 67 and continue with: 678 / 86

Moving on to step 3:
If we divide 678 by 86, we get 7 and a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 602 from 678 to get 76.
Fetch the next digit (2) from the dividend, attach it to 76 and continue: 762 / 86

Going ahead to step 4:
762 divided by 86 is 8 with a remainder of 74.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we subtract 688 from 762, we get 74.
Fetch the next digit (6) from the dividend, attach it to 74 and continue: 746 / 86

Let's proceed to step 5:
If we divide 746 by 86, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 788.0
Subtracting 688 from 746 leaves us with 58.
Fetch the next digit (3) from the dividend, attach it to 58 and continue: 583 / 86

Going ahead to step 6:
If we divide 583 by 86, we get 6 and a remainder of 67.
The next digit of our result is 6. 
Result so far: 7886.0
Deduct 516 from 583 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
86 can be fit into 670 7 times, resulting in a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 7886.7
The remainder is 68 after subtracting 602 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 8:
86 goes into 680 7 times with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 7886.77
The remainder is 78 after subtracting 602 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

The final result is 7886.77 with a remainder of 0.078.
