916975 divided by 86 
The aim is to understand the frequency of 86 in 916975.

Moving on to step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 86

Going ahead to step 2:
86 can be fit into 91 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 5 after subtracting 86 from 91.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 86

Going ahead to step 3:
86 can be fit into 56 0 times, resulting in a remainder of 56.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 56 after subtracting 0 from 56.
Grab the next digit (9) from the dividend, add it to 56, then carry on: 569 / 86

Step 4:
569 divided by 86 is 6 with a remainder of 53.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we subtract 516 from 569, we get 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 86

Step 5:
The number 86 fits into 537 6 times, leaving a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 1066.0
Subtracting 516 from 537 leaves us with 21.
Bring next digit (5) of the dividend behind the 21 and repeat the process: 215 / 86

On to step 6:
If we divide 215 by 86, we get 2 and a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 10662.0
The remainder is 43 after subtracting 172 from 215.
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:
If we divide 430 by 86, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10662.5
The remainder is 0 after subtracting 430 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
86 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10662.5
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.

Going ahead to step 9:
86 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10662.5
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.

Our division results in 10662.5 with a remaining 0.0.
