389010 ÷ 8 
The aim is to understand the frequency of 8 in 389010.

Step 1:
8 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 8

On to step 2:
8 goes into 38 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 32 from 38 to get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 8

Let's proceed to step 3:
The number 8 fits into 69 8 times, leaving a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtracting 64 from 69 leaves us with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 8

Advancing to step 4:
8 can be fit into 50 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 486.0
Subtracting 48 from 50 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 8

Advancing to step 5:
8 goes into 21 2 times with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 4862.0
Subtract 16 from 21 to get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 8

Step 6:
When dividing 50 by 8, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 48626.0
Subtract 48 from 50 to 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.

Moving on to step 7:
8 goes into 20 2 times with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 48626.2
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.

Advancing 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: 48626.25
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:
0 divided by 8 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48626.25
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.

Advancing to step 10:
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: 48626.25
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.

The final result is 48626.25 with a remainder of 0.0.
