649099 ÷ 86 
The aim is to understand the frequency of 86 in 649099.

Step 1:
The number 86 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 86

Advancing to step 2:
86 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 86

Let's proceed to step 3:
If we divide 649 by 86, we get 7 and a remainder of 47.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 602 from 649 to get 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 86

On to step 4:
The number 86 fits into 470 5 times, leaving a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Deduct 430 from 470 and we're left with 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 86

Moving on to step 5:
86 can be fit into 409 4 times, resulting in a remainder of 65.
Put 4 as the next digit of the answer. 
Result so far: 754.0
Subtract 344 from 409 to get 65.
Append the next digit (9) from the dividend to 65 and continue with: 659 / 86

Let's proceed to step 6:
86 goes into 659 7 times with a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 7547.0
The remainder is 57 after subtracting 602 from 659.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
86 goes into 570 6 times with a remainder of 54.
The next digit of our result is 6. 
Result so far: 7547.6
If we take 516 away from 570, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 8:
The number 86 fits into 540 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 7547.66
If we take 516 away from 540, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 7547.66 with a remaining 0.024.
