Let's divide 639541 by 33
The aim is to understand the frequency of 33 in 639541.

Advancing to step 1:
The number 33 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 33

Going ahead to step 2:
When dividing 63 by 33, we get 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 33 away from 63, we end up with 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 33

On to step 3:
If we divide 309 by 33, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 19.0
Subtract 297 from 309 to get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 33

Advancing to step 4:
33 can be fit into 125 3 times, resulting in a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 193.0
Subtracting 99 from 125 leaves us with 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 33

Step 5:
264 divided by 33 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1938.0
If we take 264 away from 264, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 33

Step 6:
When dividing 1 by 33, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 19380.0
Deduct 0 from 1 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
The number 33 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 19380.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
When dividing 100 by 33, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 19380.03
If we take 99 away from 100, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
When dividing 10 by 33, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19380.03
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
100 divided by 33 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 19380.0303
Subtracting 99 from 100 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 11:
33 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19380.0303
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
The number 33 fits into 100 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 19380.030303
The remainder is 1 after subtracting 99 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
If we divide 10 by 33, we get 0 and a remainder of 10.
The next digit of our result is 0. 
Result so far: 19380.030303
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 14:
If we divide 100 by 33, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 19380.03030303
If we subtract 99 from 100, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 19380.03030303, with a leftover of 1e-09.
