Let's divide 35687774 by 339
The aim is to understand the frequency of 339 in 35687774.

Step 1:
When dividing 3 by 339, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 339

Let's proceed to step 2:
339 goes into 35 0 times with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Fetch the next digit (6) from the dividend, attach it to 35 and continue: 356 / 339

Step 3:
339 can be fit into 356 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 17 after subtracting 339 from 356.
Include the next digit (8) from the dividend after 17, then repeat: 178 / 339

Moving on to step 4:
The number 339 fits into 178 0 times, leaving a remainder of 178.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 178 after subtracting 0 from 178.
Include the next digit (7) from the dividend after 178, then repeat: 1787 / 339

Advancing to step 5:
When dividing 1787 by 339, we get 5 with a remainder of 92.
Write down 5 as next digit of the result. 
Result so far: 105.0
If we take 1695 away from 1787, we end up with 92.
Bring next digit (7) of the dividend behind the 92 and repeat the process: 927 / 339

Going ahead to step 6:
339 goes into 927 2 times with a remainder of 249.
Write down 2 as next digit of the result. 
Result so far: 1052.0
If we subtract 678 from 927, we get 249.
Bring next digit (7) of the dividend behind the 249 and repeat the process: 2497 / 339

Step 7:
2497 divided by 339 is 7 with a remainder of 124.
Put 7 as the next digit of the answer. 
Result so far: 10527.0
Subtracting 2373 from 2497 leaves us with 124.
Append the next digit (4) from the dividend to 124 and continue with: 1244 / 339

On to step 8:
The number 339 fits into 1244 3 times, leaving a remainder of 227.
Record the quotient 3 as the next digit in the result. 
Result so far: 105273.0
Subtracting 1017 from 1244 leaves us with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 9:
339 can be fit into 2270 6 times, resulting in a remainder of 236.
The number 6 becomes the next digit in our result. 
Result so far: 105273.6
If we take 2034 away from 2270, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Advancing to step 10:
The number 339 fits into 2360 6 times, leaving a remainder of 326.
Record the quotient 6 as the next digit in the result. 
Result so far: 105273.66
Subtract 2034 from 2360 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

The final result is 105273.66 with a remainder of 0.326.
