865843 ÷ 86 
The aim is to understand the frequency of 86 in 865843.

Advancing to step 1:
The number 86 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 86

On to step 2:
If we divide 86 by 86, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 86 from 86 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 86

Advancing to step 3:
5 divided by 86 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 86

Let's proceed to step 4:
86 can be fit into 58 0 times, resulting in a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 58 and we're left with 58.
Take the next digit (4) from the dividend and append it to 58, then repeat: 584 / 86

Moving on to step 5:
If we divide 584 by 86, we get 6 and a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 1006.0
Deduct 516 from 584 and we're left with 68.
Take the next digit (3) from the dividend and append it to 68, then repeat: 683 / 86

Moving on to step 6:
If we divide 683 by 86, we get 7 and a remainder of 81.
The next digit of our result is 7. 
Result so far: 10067.0
If we subtract 602 from 683, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 7:
When dividing 810 by 86, we get 9 with a remainder of 36.
Write down 9 as next digit of the result. 
Result so far: 10067.9
Subtracting 774 from 810 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
If we divide 360 by 86, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 10067.94
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
160 divided by 86 is 1 with a remainder of 74.
The next digit of our result is 1. 
Result so far: 10067.941
If we subtract 86 from 160, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
740 divided by 86 is 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 10067.9418
If we take 688 away from 740, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 11:
The number 86 fits into 520 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 10067.94186
The remainder is 4 after subtracting 516 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
86 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10067.94186
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
If we divide 400 by 86, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 10067.9418604
Deduct 344 from 400 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 14:
If we divide 560 by 86, we get 6 and a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 10067.94186046
Subtract 516 from 560 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 10067.94186046 with a remaining 4.4e-08.
