We look at the division of 844993 by 86 
The aim is to understand the frequency of 86 in 844993.

Going ahead to step 1:
8 divided by 86 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 86

Step 2:
84 divided by 86 is 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 84 to get 84.
Append the next digit (4) from the dividend to 84 and continue with: 844 / 86

Step 3:
If we divide 844 by 86, we get 9 and a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 774 from 844 to get 70.
Append the next digit (9) from the dividend to 70 and continue with: 709 / 86

Going ahead to step 4:
If we divide 709 by 86, we get 8 and a remainder of 21.
Write down 8 as next digit of the result. 
Result so far: 98.0
Subtracting 688 from 709 leaves us with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 86

On to step 5:
If we divide 219 by 86, we get 2 and a remainder of 47.
Write down 2 as next digit of the result. 
Result so far: 982.0
If we take 172 away from 219, we end up with 47.
Take the next digit (3) from the dividend and append it to 47, then repeat: 473 / 86

Step 6:
86 goes into 473 5 times with a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 9825.0
If we take 430 away from 473, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
When dividing 430 by 86, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 9825.5
If we subtract 430 from 430, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
If we divide 0 by 86, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9825.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
When dividing 0 by 86, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9825.5
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 9825.5 with a remainder of 0.0.
