Let's divide 436765 by 86
The aim is to understand the frequency of 86 in 436765.

Advancing to step 1:
If we divide 4 by 86, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 86

Going ahead to step 2:
86 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 86

Let's proceed to step 3:
436 divided by 86 is 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 430 from 436 and we're left with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 86

Moving on to step 4:
If we divide 67 by 86, we get 0 and a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 67 to get 67.
Append the next digit (6) from the dividend to 67 and continue with: 676 / 86

Step 5:
86 can be fit into 676 7 times, resulting in a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 507.0
Deduct 602 from 676 and we're left with 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 86

Let's proceed to step 6:
If we divide 745 by 86, we get 8 and a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 5078.0
If we subtract 688 from 745, we get 57.
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:
The number 86 fits into 570 6 times, leaving a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 5078.6
Subtract 516 from 570 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 8:
If we divide 540 by 86, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 5078.66
The remainder is 24 after subtracting 516 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 5078.66, with a leftover of 0.024.
