618635 ÷ 33 
The aim is to understand the frequency of 33 in 618635.

Let's proceed to step 1:
When dividing 6 by 33, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 33

Let's proceed to step 2:
If we divide 61 by 33, we get 1 and a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 28 after subtracting 33 from 61.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 33

Step 3:
33 goes into 288 8 times with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 18.0
The remainder is 24 after subtracting 264 from 288.
Include the next digit (6) from the dividend after 24, then repeat: 246 / 33

Moving on to step 4:
If we divide 246 by 33, we get 7 and a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 187.0
Subtract 231 from 246 to get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 33

On to step 5:
When dividing 153 by 33, we get 4 with a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 1874.0
If we subtract 132 from 153, we get 21.
Grab the next digit (5) from the dividend, add it to 21, then carry on: 215 / 33

Going ahead to step 6:
If we divide 215 by 33, we get 6 and a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 18746.0
Subtracting 198 from 215 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 7:
170 divided by 33 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 18746.5
If we subtract 165 from 170, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
33 can be fit into 50 1 times, resulting in a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 18746.51
If we subtract 33 from 50, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 9:
33 goes into 170 5 times with a remainder of 5.
The next digit of our result is 5. 
Result so far: 18746.515
If we subtract 165 from 170, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
The number 33 fits into 50 1 times, leaving a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 18746.5151
The remainder is 17 after subtracting 33 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
33 goes into 170 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 18746.51515
Subtract 165 from 170 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 12:
33 goes into 50 1 times with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 18746.515151
Subtract 33 from 50 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 13:
33 can be fit into 170 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 18746.5151515
Subtract 165 from 170 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 14:
If we divide 50 by 33, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 18746.51515151
The remainder is 17 after subtracting 33 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 18746.51515151 and a remainder of 1.7e-08.
