926975 ÷ 86 
The aim is to understand the frequency of 86 in 926975.

Advancing to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 86

Going ahead to step 2:
When dividing 92 by 86, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 86 from 92 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 86

Moving on to step 3:
66 divided by 86 is 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 66 and we're left with 66.
Include the next digit (9) from the dividend after 66, then repeat: 669 / 86

Advancing to step 4:
86 goes into 669 7 times with a remainder of 67.
Record the quotient 7 as the next digit in the result. 
Result so far: 107.0
If we subtract 602 from 669, we get 67.
Append the next digit (7) from the dividend to 67 and continue with: 677 / 86

Let's proceed to step 5:
When dividing 677 by 86, we get 7 with a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 1077.0
If we subtract 602 from 677, we get 75.
Include the next digit (5) from the dividend after 75, then repeat: 755 / 86

On to step 6:
86 can be fit into 755 8 times, resulting in a remainder of 67.
Use 8 as the next digit of our solution. 
Result so far: 10778.0
Subtracting 688 from 755 leaves us 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.

Moving on to step 7:
86 goes into 670 7 times with a remainder of 68.
Use 7 as the next digit of our solution. 
Result so far: 10778.7
Subtract 602 from 670 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
680 divided by 86 is 7 with a remainder of 78.
Write down 7 as next digit of the result. 
Result so far: 10778.77
Subtracting 602 from 680 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 10778.77 and a remainder of 0.078.
