We're dividing 333093 by 39 
The aim is to understand the frequency of 39 in 333093.

Advancing to step 1:
If we divide 3 by 39, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 39

Going ahead to step 2:
If we divide 33 by 39, we get 0 and a remainder of 33.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Include the next digit (3) from the dividend after 33, then repeat: 333 / 39

Moving on to step 3:
The number 39 fits into 333 8 times, leaving a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 312 from 333 and we're left with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 39

Let's proceed to step 4:
39 goes into 210 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 195 from 210 to get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 39

On to step 5:
If we divide 159 by 39, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 854.0
Subtracting 156 from 159 leaves us with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 39

On to step 6:
39 can be fit into 33 0 times, resulting in a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 8540.0
If we subtract 0 from 33, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 7:
39 goes into 330 8 times with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 8540.8
Subtracting 312 from 330 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 8540.84
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 8540.846
Deduct 234 from 240 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
If we divide 60 by 39, we get 1 and a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 8540.8461
Subtracting 39 from 60 leaves us 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 11:
210 divided by 39 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8540.84615
Subtract 195 from 210 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 12:
39 goes into 150 3 times with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 8540.846153
The remainder is 33 after subtracting 117 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 13:
39 goes into 330 8 times with a remainder of 18.
The next digit of our result is 8. 
Result so far: 8540.8461538
Subtract 312 from 330 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 14:
180 divided by 39 is 4 with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 8540.84615384
If we take 156 away from 180, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 8540.84615384 with a remainder of 2.4e-08.
