We look at the division of 694458 by 8 
The aim is to understand the frequency of 8 in 694458.

Let's proceed to step 1:
The number 8 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 8

Going ahead to step 2:
69 divided by 8 is 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 64 from 69 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 8

Going ahead to step 3:
If we divide 54 by 8, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
If we take 48 away from 54, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 8

Going ahead to step 4:
64 divided by 8 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 868.0
If we take 64 away from 64, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 8

Let's proceed to step 5:
When dividing 5 by 8, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 8680.0
If we subtract 0 from 5, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 8

Let's proceed to step 6:
When dividing 58 by 8, we get 7 with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 86807.0
If we subtract 56 from 58, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
When dividing 20 by 8, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 86807.2
Deduct 16 from 20 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
40 divided by 8 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 86807.25
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.

Going ahead to step 9:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 86807.25
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.

On to step 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 86807.25
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.

The final outcome is 86807.25, with a leftover of 0.0.
