We look at the division of 656994 by 33 
The aim is to understand the frequency of 33 in 656994.

On to step 1:
33 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 33

Advancing to step 2:
If we divide 65 by 33, we get 1 and a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 33 from 65, we get 32.
Include the next digit (6) from the dividend after 32, then repeat: 326 / 33

Going ahead to step 3:
326 divided by 33 is 9 with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 297 from 326 and we're left with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 33

Moving on to step 4:
33 goes into 299 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 199.0
Deduct 297 from 299 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 33

Step 5:
29 divided by 33 is 0 with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 1990.0
If we take 0 away from 29, we end up with 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 33

Step 6:
294 divided by 33 is 8 with a remainder of 30.
Use 8 as the next digit of our solution. 
Result so far: 19908.0
Subtract 264 from 294 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
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: 19908.9
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.

On to step 8:
33 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 19908.9
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.

Moving on to step 9:
When dividing 300 by 33, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 19908.909
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.

Advancing to step 10:
If we divide 30 by 33, we get 0 and a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 19908.909
If we subtract 0 from 30, we get 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 11:
300 divided by 33 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 19908.90909
Subtract 297 from 300 to 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.

Going ahead to step 12:
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: 19908.90909
If we take 0 away from 30, we end up 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.

On to step 13:
33 can be fit into 300 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 19908.9090909
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 14:
33 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 19908.9090909
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 19908.9090909, and the remainder is 3e-08.
