We look at the division of 33983579 by 338 
The aim is to understand the frequency of 338 in 33983579.

Let's proceed to step 1:
If we divide 3 by 338, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 338

Step 2:
338 can be fit into 33 0 times, resulting in 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.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 338

Moving on to step 3:
338 goes into 339 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 338 from 339 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 338

Moving on to step 4:
The number 338 fits into 18 0 times, leaving a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 18, we end up with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 338

Let's proceed to step 5:
The number 338 fits into 183 0 times, leaving a remainder of 183.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 183 and we're left with 183.
Append the next digit (5) from the dividend to 183 and continue with: 1835 / 338

Going ahead to step 6:
338 can be fit into 1835 5 times, resulting in a remainder of 145.
The next digit of our result is 5. 
Result so far: 1005.0
Deduct 1690 from 1835 and we're left with 145.
Take the next digit (7) from the dividend and append it to 145, then repeat: 1457 / 338

Moving on to step 7:
If we divide 1457 by 338, we get 4 and a remainder of 105.
Write down 4 as next digit of the result. 
Result so far: 10054.0
Subtract 1352 from 1457 to get 105.
Bring next digit (9) of the dividend behind the 105 and repeat the process: 1059 / 338

Let's proceed to step 8:
The number 338 fits into 1059 3 times, leaving a remainder of 45.
Record the quotient 3 as the next digit in the result. 
Result so far: 100543.0
If we take 1014 away from 1059, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
450 divided by 338 is 1 with a remainder of 112.
Use 1 as the next digit of our solution. 
Result so far: 100543.1
Subtracting 338 from 450 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 10:
1120 divided by 338 is 3 with a remainder of 106.
Use 3 as the next digit of our solution. 
Result so far: 100543.13
Subtract 1014 from 1120 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 11:
1060 divided by 338 is 3 with a remainder of 46.
The next digit of our result is 3. 
Result so far: 100543.133
Subtract 1014 from 1060 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 100543.133 with a remaining 0.0046.
