839400 divided by 33 
The aim is to understand the frequency of 33 in 839400.

Let's proceed to step 1:
When dividing 8 by 33, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 33

On to step 2:
33 can be fit into 83 2 times, resulting in a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 66 away from 83, we end up with 17.
Fetch the next digit (9) from the dividend, attach it to 17 and continue: 179 / 33

Step 3:
The number 33 fits into 179 5 times, leaving a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 165 from 179 leaves us with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 33

Advancing to step 4:
When dividing 144 by 33, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtract 132 from 144 to get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 33

Going ahead to step 5:
33 can be fit into 120 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 2543.0
If we take 99 away from 120, we end up with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 33

Step 6:
33 can be fit into 210 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 25436.0
Deduct 198 from 210 and we're left 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.

Going ahead to step 7:
When dividing 120 by 33, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 25436.3
Deduct 99 from 120 and we're left 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.

Going ahead to step 8:
33 can be fit into 210 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 25436.36
The remainder is 12 after subtracting 198 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
33 goes into 120 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 25436.363
If we subtract 99 from 120, we 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.

On to step 10:
When dividing 210 by 33, we get 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 25436.3636
The remainder is 12 after subtracting 198 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 11:
33 goes into 120 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 25436.36363
Deduct 99 from 120 and we're left 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.

On to step 12:
210 divided by 33 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 25436.363636
The remainder is 12 after subtracting 198 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 13:
The number 33 fits into 120 3 times, leaving a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 25436.3636363
Deduct 99 from 120 and we're left 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 14:
The number 33 fits into 210 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 25436.36363636
The remainder is 12 after subtracting 198 from 210.
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 25436.36363636 and a remainder of 1.2e-08.
