Let's divide 661548 by 33
The aim is to understand the frequency of 33 in 661548.

Advancing to step 1:
When dividing 6 by 33, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 33

Step 2:
33 can be fit into 66 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 66 from 66 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 33

Moving on to step 3:
If we divide 1 by 33, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 33

On to step 4:
33 goes into 15 0 times with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 200.0
If we take 0 away from 15, we end up with 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 33

Advancing to step 5:
154 divided by 33 is 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 2004.0
The remainder is 22 after subtracting 132 from 154.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 33

Moving on to step 6:
The number 33 fits into 228 6 times, leaving a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 20046.0
Deduct 198 from 228 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.

On to step 7:
If we divide 300 by 33, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 20046.9
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.

Let's proceed to step 8:
If we divide 30 by 33, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 20046.9
Subtract 0 from 30 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.

On to step 9:
300 divided by 33 is 9 with a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 20046.909
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.

Going ahead to step 10:
30 divided by 33 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 20046.909
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.

Let's proceed to step 11:
When dividing 300 by 33, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 20046.90909
If we take 297 away from 300, we end up 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 12:
30 divided by 33 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 20046.90909
The remainder is 30 after subtracting 0 from 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 13:
When dividing 300 by 33, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 20046.9090909
The remainder is 3 after subtracting 297 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
30 divided by 33 is 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 20046.9090909
Subtracting 0 from 30 leaves us 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.

The quotient of the division is 20046.9090909, and the remainder is 3e-08.
