587238 ÷ 86 
The aim is to understand the frequency of 86 in 587238.

Advancing to step 1:
86 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 86

Let's proceed to step 2:
86 can be fit into 58 0 times, resulting in a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Include the next digit (7) from the dividend after 58, then repeat: 587 / 86

On to step 3:
If we divide 587 by 86, we get 6 and a remainder of 71.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 516 from 587, we get 71.
Append the next digit (2) from the dividend to 71 and continue with: 712 / 86

Let's proceed to step 4:
The number 86 fits into 712 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Deduct 688 from 712 and we're left with 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 86

Going ahead to step 5:
86 goes into 243 2 times with a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 682.0
If we subtract 172 from 243, we get 71.
Take the next digit (8) from the dividend and append it to 71, then repeat: 718 / 86

Going ahead to step 6:
86 goes into 718 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 6828.0
If we subtract 688 from 718, 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 7:
300 divided by 86 is 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 6828.3
The remainder is 42 after subtracting 258 from 300.
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 8:
420 divided by 86 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 6828.34
The remainder is 76 after subtracting 344 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 9:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 6828.348
Subtract 688 from 760 to 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.

Let's proceed to step 10:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Put 8 as the next digit of the answer. 
Result so far: 6828.3488
Deduct 688 from 720 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 6828.3488, and the remainder is 0.00032.
