We're dividing 103161 by 33 
The aim is to understand the frequency of 33 in 103161.

Step 1:
The number 33 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 33

Let's proceed to step 2:
If we divide 10 by 33, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 33

Going ahead to step 3:
33 goes into 103 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 99 from 103, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 33

Step 4:
When dividing 41 by 33, we get 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtracting 33 from 41 leaves us with 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 33

Moving on to step 5:
The number 33 fits into 86 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 312.0
Deduct 66 from 86 and we're left with 20.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 33

On to step 6:
201 divided by 33 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 3126.0
The remainder is 3 after subtracting 198 from 201.
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 7:
The number 33 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 3126.0
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.

Moving on to step 8:
If we divide 300 by 33, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 3126.09
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.

Going ahead to step 9:
33 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 3126.09
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.

Going ahead to step 10:
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: 3126.0909
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.

On to step 11:
When dividing 30 by 33, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 3126.0909
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.

On to step 12:
33 can be fit into 300 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 3126.090909
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 13:
If we divide 30 by 33, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 3126.090909
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.

Going ahead to step 14:
If we divide 300 by 33, we get 9 and a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 3126.09090909
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.

After the division, we end up with 3126.09090909 and a remainder of 3e-09.
