Let's divide 698409 by 8
The aim is to understand the frequency of 8 in 698409.

Moving on to step 1:
8 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 8

On to step 2:
If we divide 69 by 8, we get 8 and a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 64 from 69 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 8

On to step 3:
58 divided by 8 is 7 with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 87.0
Subtract 56 from 58 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 8

Step 4:
When dividing 24 by 8, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 873.0
Subtracting 24 from 24 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 8

Let's proceed to step 5:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8730.0
If we subtract 0 from 0, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 8

Advancing to step 6:
If we divide 9 by 8, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 87301.0
Deduct 8 from 9 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
10 divided by 8 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 87301.1
If we take 8 away from 10, we end up 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.

Let's proceed to step 8:
8 can be fit into 20 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 87301.12
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.

Going ahead to step 9:
8 goes into 40 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 87301.125
If we take 40 away from 40, 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 10:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 87301.125
Subtracting 0 from 0 leaves us 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 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 87301.125
If we take 0 away from 0, 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.

The final outcome is 87301.125, with a leftover of 0.0.
