We look at the division of 549817 by 33 
The aim is to understand the frequency of 33 in 549817.

Step 1:
33 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 33

On to step 2:
33 goes into 54 1 times with a remainder of 21.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 21 after subtracting 33 from 54.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 33

Moving on to step 3:
If we divide 219 by 33, we get 6 and a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 16.0
The remainder is 21 after subtracting 198 from 219.
Bring next digit (8) of the dividend behind the 21 and repeat the process: 218 / 33

Going ahead to step 4:
If we divide 218 by 33, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 166.0
If we subtract 198 from 218, we get 20.
Grab the next digit (1) from the dividend, add it to 20, then carry on: 201 / 33

On to step 5:
When dividing 201 by 33, we get 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 1666.0
Subtract 198 from 201 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 33

Moving on to step 6:
33 goes into 37 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 16661.0
Deduct 33 from 37 and we're left with 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:
33 can be fit into 40 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 16661.1
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
70 divided by 33 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 16661.12
The remainder is 4 after subtracting 66 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
33 goes into 40 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 16661.121
If we subtract 33 from 40, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
The number 33 fits into 70 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 16661.1212
Subtract 66 from 70 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.

On to step 11:
33 goes into 40 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 16661.12121
Deduct 33 from 40 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
33 can be fit into 70 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 16661.121212
Subtracting 66 from 70 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
When dividing 40 by 33, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 16661.1212121
If we take 33 away from 40, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
When dividing 70 by 33, we get 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 16661.12121212
The remainder is 4 after subtracting 66 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 16661.12121212, with a leftover of 4e-09.
