We're dividing 870776 by 17 
The aim is to understand the frequency of 17 in 870776.

Let's proceed to step 1:
If we divide 8 by 17, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 17

Let's proceed to step 2:
87 divided by 17 is 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 85 away from 87, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 17

Let's proceed to step 3:
The number 17 fits into 20 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 51.0
The remainder is 3 after subtracting 17 from 20.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 17

Step 4:
If we divide 37 by 17, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 512.0
Subtract 34 from 37 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 17

Moving on to step 5:
37 divided by 17 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 5122.0
Subtract 34 from 37 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 17

Advancing to step 6:
17 can be fit into 36 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 51222.0
Deduct 34 from 36 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
20 divided by 17 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 51222.1
Deduct 17 from 20 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 8:
30 divided by 17 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 51222.11
Deduct 17 from 30 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 51222.11 with a remainder of 0.013.
