We divide 718586 by 8
The aim is to understand the frequency of 8 in 718586.

Let's proceed to step 1:
If we divide 7 by 8, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 8

Let's proceed to step 2:
The number 8 fits into 71 8 times, leaving a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 64 away from 71, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 8

Advancing to step 3:
If we divide 78 by 8, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 89.0
Subtract 72 from 78 to get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 8

Going ahead to step 4:
The number 8 fits into 65 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 898.0
Deduct 64 from 65 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 8

Let's proceed to step 5:
8 can be fit into 18 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 8982.0
Subtract 16 from 18 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 8

On to step 6:
26 divided by 8 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 89823.0
The remainder is 2 after subtracting 24 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 89823.2
Subtract 16 from 20 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
8 goes into 40 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 89823.25
Subtract 40 from 40 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.

Moving on to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 89823.25
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.

Step 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 89823.25
If we subtract 0 from 0, 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.

After the division, we end up with 89823.25 and a remainder of 0.0.
