We're dividing 799836 by 86 
The aim is to understand the frequency of 86 in 799836.

Moving on to step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 86

On to step 2:
When dividing 79 by 86, we get 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Include the next digit (9) from the dividend after 79, then repeat: 799 / 86

Moving on to step 3:
799 divided by 86 is 9 with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 774 away from 799, we end up with 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 86

Step 4:
86 goes into 258 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtract 258 from 258 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 86

Step 5:
3 divided by 86 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 930.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 86

Step 6:
If we divide 36 by 86, we get 0 and a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 9300.0
If we take 0 away from 36, we end up 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.

Advancing to step 7:
86 can be fit into 360 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 9300.4
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.

Moving on to step 8:
The number 86 fits into 160 1 times, leaving a remainder of 74.
Use 1 as the next digit of our solution. 
Result so far: 9300.41
The remainder is 74 after subtracting 86 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
If we divide 740 by 86, we get 8 and a remainder of 52.
The next digit of our result is 8. 
Result so far: 9300.418
Subtracting 688 from 740 leaves us 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 10:
86 goes into 520 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 9300.4186
Deduct 516 from 520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
If we divide 40 by 86, we get 0 and a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 9300.4186
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
86 goes into 400 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 9300.418604
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
The number 86 fits into 560 6 times, leaving a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 9300.4186046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
If we divide 440 by 86, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 9300.41860465
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 9300.41860465 and a remainder of 1e-08.
