577416 divided by 8 
The aim is to understand the frequency of 8 in 577416.

Going ahead to step 1:
8 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 8

Step 2:
8 can be fit into 57 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 56 from 57, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 8

Moving on to step 3:
8 goes into 17 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
The remainder is 1 after subtracting 16 from 17.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 8

Moving on to step 4:
The number 8 fits into 14 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 721.0
Deduct 8 from 14 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 8

On to step 5:
61 divided by 8 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 7217.0
Subtract 56 from 61 to get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 8

On to step 6:
The number 8 fits into 56 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 72177.0
If we take 56 away from 56, we end up 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.

Moving on to step 7:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 72177.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 72177.0
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 72177.0 with a remainder of 0.0.
