We look at the division of 421118 by 33 
The aim is to understand the frequency of 33 in 421118.

Going ahead to step 1:
33 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 33

Moving on to step 2:
If we divide 42 by 33, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 9 after subtracting 33 from 42.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 33

Step 3:
33 goes into 91 2 times with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 66 from 91 to get 25.
Append the next digit (1) from the dividend to 25 and continue with: 251 / 33

Going ahead to step 4:
The number 33 fits into 251 7 times, leaving a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
If we take 231 away from 251, we end up with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 33

Going ahead to step 5:
33 can be fit into 201 6 times, resulting in a remainder of 3.
The next digit of our result is 6. 
Result so far: 1276.0
Subtract 198 from 201 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 33

Advancing to step 6:
If we divide 38 by 33, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 12761.0
Subtracting 33 from 38 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
50 divided by 33 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 12761.1
The remainder is 17 after subtracting 33 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 8:
170 divided by 33 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12761.15
Subtracting 165 from 170 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 33, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 12761.151
Subtract 33 from 50 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 10:
If we divide 170 by 33, we get 5 and a remainder of 5.
The next digit of our result is 5. 
Result so far: 12761.1515
Subtract 165 from 170 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
If we divide 50 by 33, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 12761.15151
If we subtract 33 from 50, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 12:
33 goes into 170 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12761.151515
If we take 165 away from 170, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 13:
33 goes into 50 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 12761.1515151
Subtract 33 from 50 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 14:
If we divide 170 by 33, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 12761.15151515
Deduct 165 from 170 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 12761.15151515 and a remainder of 5e-09.
