We look at the division of 513957 by 33 
The aim is to understand the frequency of 33 in 513957.

Let's proceed to step 1:
5 divided by 33 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 33

Going ahead to step 2:
If we divide 51 by 33, we get 1 and a remainder of 18.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 33 from 51 and we're left with 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 33

Advancing to step 3:
183 divided by 33 is 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 18 after subtracting 165 from 183.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 33

Step 4:
33 can be fit into 189 5 times, resulting in a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Deduct 165 from 189 and we're left with 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 33

Advancing to step 5:
The number 33 fits into 245 7 times, leaving a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 1557.0
Deduct 231 from 245 and we're left with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 33

On to step 6:
When dividing 147 by 33, we get 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 15574.0
Subtracting 132 from 147 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
33 goes into 150 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 15574.4
Subtracting 132 from 150 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
33 can be fit into 180 5 times, resulting in a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 15574.45
Subtract 165 from 180 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
When dividing 150 by 33, we get 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 15574.454
If we subtract 132 from 150, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
If we divide 180 by 33, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 15574.4545
Deduct 165 from 180 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
When dividing 150 by 33, we get 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 15574.45454
Subtract 132 from 150 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
33 goes into 180 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 15574.454545
Subtract 165 from 180 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 13:
33 can be fit into 150 4 times, resulting in a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 15574.4545454
The remainder is 18 after subtracting 132 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 14:
33 can be fit into 180 5 times, resulting in a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15574.45454545
If we subtract 165 from 180, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.
