We look at the division of 510856 by 33 
The aim is to understand the frequency of 33 in 510856.

Advancing to step 1:
The number 33 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 33

On to step 2:
The number 33 fits into 51 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 33 from 51 and we're left with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 33

Going ahead to step 3:
180 divided by 33 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 165 from 180 leaves us with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 33

On to step 4:
33 goes into 158 4 times with a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 154.0
If we subtract 132 from 158, we get 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 33

Step 5:
The number 33 fits into 265 8 times, leaving a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 1548.0
If we subtract 264 from 265, we get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 33

Advancing to step 6:
When dividing 16 by 33, we get 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 15480.0
Subtracting 0 from 16 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
33 can be fit into 160 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 15480.4
Deduct 132 from 160 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
If we divide 280 by 33, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 15480.48
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
The number 33 fits into 160 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 15480.484
If we subtract 132 from 160, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 10:
33 goes into 280 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 15480.4848
If we take 264 away from 280, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
When dividing 160 by 33, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 15480.48484
Subtracting 132 from 160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
The number 33 fits into 280 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 15480.484848
The remainder is 16 after subtracting 264 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 13:
When dividing 160 by 33, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 15480.4848484
If we take 132 away from 160, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 14:
When dividing 280 by 33, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 15480.48484848
Deduct 264 from 280 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 15480.48484848 with a remaining 1.6e-08.
