684770 ÷ 8 
The aim is to understand the frequency of 8 in 684770.

On to step 1:
6 divided by 8 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 8

On to step 2:
If we divide 68 by 8, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 64 away from 68, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 8

Step 3:
When dividing 44 by 8, we get 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 40 from 44 to get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 8

Advancing to step 4:
8 goes into 47 5 times with a remainder of 7.
The number 5 becomes the next digit in our result. 
Result so far: 855.0
Subtracting 40 from 47 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 8

Let's proceed to step 5:
If we divide 77 by 8, we get 9 and a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 8559.0
Subtract 72 from 77 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 8

Advancing to step 6:
50 divided by 8 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 85596.0
If we take 48 away from 50, 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 7:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 85596.2
If we subtract 16 from 20, we 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 can be fit into 40 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 85596.25
If we subtract 40 from 40, 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.

Going ahead to step 9:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 85596.25
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.

On to step 10:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 85596.25
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.

The final outcome is 85596.25, with a leftover of 0.0.
