We look at the division of 516658 by 33 
The aim is to understand the frequency of 33 in 516658.

Going ahead to step 1:
5 divided by 33 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 33

On to step 2:
If we divide 51 by 33, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 33 from 51, we get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 33

Step 3:
If we divide 186 by 33, we get 5 and a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 165 from 186 leaves us with 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 33

On to step 4:
The number 33 fits into 216 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 156.0
The remainder is 18 after subtracting 198 from 216.
Include the next digit (5) from the dividend after 18, then repeat: 185 / 33

Step 5:
If we divide 185 by 33, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 1565.0
Subtract 165 from 185 to get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 33

Going ahead to step 6:
33 goes into 208 6 times with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 15656.0
Subtract 198 from 208 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 33 fits into 100 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 15656.3
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
When dividing 10 by 33, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15656.3
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
33 goes into 100 3 times with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 15656.303
Subtract 99 from 100 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
When dividing 10 by 33, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 15656.303
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
When dividing 100 by 33, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 15656.30303
Deduct 99 from 100 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
If we divide 10 by 33, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 15656.30303
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
The number 33 fits into 100 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 15656.3030303
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 14:
When dividing 10 by 33, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 15656.3030303
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 15656.3030303 and a remainder of 1e-08.
