We're dividing 341397 by 33 
The aim is to understand the frequency of 33 in 341397.

Step 1:
The number 33 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 33

Going ahead to step 2:
When dividing 34 by 33, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 33 from 34.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 33

Going ahead to step 3:
11 divided by 33 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 11, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 33

On to step 4:
113 divided by 33 is 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 103.0
If we subtract 99 from 113, we get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 33

On to step 5:
When dividing 149 by 33, we get 4 with a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 1034.0
Subtracting 132 from 149 leaves us with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 33

Going ahead to step 6:
177 divided by 33 is 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 10345.0
If we take 165 away from 177, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 33 fits into 120 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 10345.3
If we take 99 away from 120, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
If we divide 210 by 33, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 10345.36
If we subtract 198 from 210, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
The number 33 fits into 120 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 10345.363
Subtract 99 from 120 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 10:
210 divided by 33 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 10345.3636
If we subtract 198 from 210, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 11:
If we divide 120 by 33, we get 3 and a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 10345.36363
If we take 99 away from 120, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
The number 33 fits into 210 6 times, leaving a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 10345.363636
Subtract 198 from 210 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 13:
120 divided by 33 is 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 10345.3636363
Subtract 99 from 120 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
When dividing 210 by 33, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 10345.36363636
If we subtract 198 from 210, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 10345.36363636 and a remainder of 1.2e-08.
