186428 ÷ 8 
The aim is to understand the frequency of 8 in 186428.

On to step 1:
The number 8 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 8

Moving on to step 2:
8 can be fit into 18 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 16 from 18 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 8

Going ahead to step 3:
If we divide 26 by 8, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
The remainder is 2 after subtracting 24 from 26.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 8

Advancing to step 4:
If we divide 24 by 8, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
Subtract 24 from 24 to get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 8

Let's proceed to step 5:
When dividing 2 by 8, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 2330.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 8

Advancing to step 6:
When dividing 28 by 8, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 23303.0
Subtract 24 from 28 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.

Let's proceed to step 7:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 23303.5
The remainder is 0 after subtracting 40 from 40.
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 8:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23303.5
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.

Advancing 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: 23303.5
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 23303.5, with a leftover of 0.0.
