166290 ÷ 5 
The aim is to understand the frequency of 5 in 166290.

Let's proceed to step 1:
5 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 5

Moving on to step 2:
The number 5 fits into 16 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 15 from 16 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 5

Advancing to step 3:
5 can be fit into 16 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 33.0
Subtract 15 from 16 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 5

On to step 4:
If we divide 12 by 5, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 332.0
If we subtract 10 from 12, we get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 5

Going ahead to step 5:
5 can be fit into 29 5 times, resulting in a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 3325.0
The remainder is 4 after subtracting 25 from 29.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 5

Moving on to step 6:
5 goes into 40 8 times with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 33258.0
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.

Let's proceed to step 7:
The number 5 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 33258.0
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.

Step 8:
If we divide 0 by 5, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 33258.0
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.

After the division, we end up with 33258.0 and a remainder of 0.0.
