We divide 168930 by 8
The aim is to understand the frequency of 8 in 168930.

Step 1:
1 divided by 8 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 8

Moving on to step 2:
If we divide 16 by 8, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 16 from 16, we get 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 8

Advancing to step 3:
When dividing 8 by 8, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Subtract 8 from 8 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 8

Advancing to step 4:
9 divided by 8 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Deduct 8 from 9 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 8

Step 5:
When dividing 13 by 8, we get 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 2111.0
Deduct 8 from 13 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 8

Moving on to step 6:
8 goes into 50 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 21116.0
If we subtract 48 from 50, 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.

Advancing 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: 21116.2
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.

Step 8:
40 divided by 8 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 21116.25
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.

On to step 9:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21116.25
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 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 21116.25
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 result is 21116.25 with a remainder of 0.0.
