We look at the division of 782103 by 33 
The aim is to understand the frequency of 33 in 782103.

Advancing to step 1:
If we divide 7 by 33, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 33

Let's proceed to step 2:
33 goes into 78 2 times with a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 66 from 78 and we're left with 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 33

Let's proceed to step 3:
If we divide 122 by 33, we get 3 and a remainder of 23.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Subtracting 99 from 122 leaves us with 23.
Include the next digit (1) from the dividend after 23, then repeat: 231 / 33

On to step 4:
If we divide 231 by 33, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 237.0
Subtract 231 from 231 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 33

Step 5:
0 divided by 33 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2370.0
If we take 0 away from 0, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 33

Advancing to step 6:
33 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 23700.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 33, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 23700.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
33 goes into 300 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 23700.09
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 9:
When dividing 30 by 33, we get 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 23700.09
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
If we divide 300 by 33, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 23700.0909
Deduct 297 from 300 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
33 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 23700.0909
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
If we divide 300 by 33, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 23700.090909
Subtracting 297 from 300 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 13:
30 divided by 33 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 23700.090909
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 14:
When dividing 300 by 33, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 23700.09090909
If we subtract 297 from 300, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Our division results in 23700.09090909 with a remaining 3e-09.
