We're dividing 338953 by 49 
The aim is to understand the frequency of 49 in 338953.

Step 1:
If we divide 3 by 49, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 49

On to step 2:
49 goes into 33 0 times with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 49

Advancing to step 3:
The number 49 fits into 338 6 times, leaving a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 294 from 338 to get 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 49

Let's proceed to step 4:
49 goes into 449 9 times with a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we take 441 away from 449, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 49

On to step 5:
85 divided by 49 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 691.0
The remainder is 36 after subtracting 49 from 85.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 49

On to step 6:
49 goes into 363 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 6917.0
Subtracting 343 from 363 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
49 can be fit into 200 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 6917.4
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
If we divide 40 by 49, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6917.4
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
If we divide 400 by 49, we get 8 and a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 6917.408
If we subtract 392 from 400, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 49 fits into 80 1 times, leaving a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 6917.4081
Deduct 49 from 80 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
49 can be fit into 310 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 6917.40816
Deduct 294 from 310 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
160 divided by 49 is 3 with a remainder of 13.
The next digit of our result is 3. 
Result so far: 6917.408163
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 13:
If we divide 130 by 49, we get 2 and a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 6917.4081632
The remainder is 32 after subtracting 98 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
The number 49 fits into 320 6 times, leaving a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 6917.40816326
If we take 294 away from 320, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 6917.40816326 with a remainder of 2.6e-08.
