We look at the division of 132660 by 4 
The aim is to understand the frequency of 4 in 132660.

Moving on to step 1:
The number 4 fits into 1 0 times, leaving 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.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 4

Moving on to step 2:
The number 4 fits into 13 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 12 from 13 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 4

Step 3:
4 goes into 12 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we subtract 12 from 12, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 4

Advancing to step 4:
If we divide 6 by 4, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 331.0
If we take 4 away from 6, we end up with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 4

Advancing to step 5:
The number 4 fits into 26 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 3316.0
Deduct 24 from 26 and we're left with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 4

Moving on to step 6:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 33165.0
If we take 20 away from 20, 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.

Let's proceed to step 7:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 33165.0
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.

On to step 8:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 33165.0
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.

Our division results in 33165.0 with a remaining 0.0.
