We're dividing 2378 by 33 
The aim is to understand the frequency of 33 in 2378.

Advancing to step 1:
If we divide 2 by 33, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 33

Let's proceed to step 2:
33 can be fit into 23 0 times, resulting in a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 23 after subtracting 0 from 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 33

Step 3:
The number 33 fits into 237 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 231 from 237, we get 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 33

Moving on to step 4:
68 divided by 33 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtract 66 from 68 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 5:
When dividing 20 by 33, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 72.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 6:
When dividing 200 by 33, we get 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 72.06
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
The number 33 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 72.06
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 33 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 72.0606
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
When dividing 20 by 33, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 72.0606
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
If we divide 200 by 33, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 72.060606
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
If we divide 20 by 33, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 72.060606
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 12:
The number 33 fits into 200 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 72.06060606
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 72.06060606, with a leftover of 2e-09.
