Let's divide 644377 by 33
The aim is to understand the frequency of 33 in 644377.

Advancing to step 1:
When dividing 6 by 33, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 33

Moving on to step 2:
33 can be fit into 64 1 times, resulting in a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 33 away from 64, we end up with 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 33

Let's proceed to step 3:
The number 33 fits into 314 9 times, leaving a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 297 from 314 to get 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 33

Step 4:
173 divided by 33 is 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 195.0
If we take 165 away from 173, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 33

On to step 5:
If we divide 87 by 33, we get 2 and a remainder of 21.
The next digit of our result is 2. 
Result so far: 1952.0
If we take 66 away from 87, we end up with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 33

Going ahead to step 6:
33 goes into 217 6 times with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 19526.0
The remainder is 19 after subtracting 198 from 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
When dividing 190 by 33, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 19526.5
If we take 165 away from 190, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
The number 33 fits into 250 7 times, leaving a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 19526.57
Deduct 231 from 250 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
The number 33 fits into 190 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 19526.575
Subtracting 165 from 190 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 10:
When dividing 250 by 33, we get 7 with a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 19526.5757
If we take 231 away from 250, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 11:
The number 33 fits into 190 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 19526.57575
The remainder is 25 after subtracting 165 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 12:
33 can be fit into 250 7 times, resulting in a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 19526.575757
If we take 231 away from 250, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
If we divide 190 by 33, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 19526.5757575
If we subtract 165 from 190, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
250 divided by 33 is 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 19526.57575757
Subtracting 231 from 250 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 19526.57575757 with a remaining 1.9e-08.
