We look at the division of 339457 by 49 
The aim is to understand the frequency of 49 in 339457.

Going ahead to step 1:
49 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 49

Moving on to step 2:
When dividing 33 by 49, we get 0 with a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 49

Going ahead to step 3:
The number 49 fits into 339 6 times, leaving a remainder of 45.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 294 from 339, we get 45.
Take the next digit (4) from the dividend and append it to 45, then repeat: 454 / 49

Advancing to step 4:
If we divide 454 by 49, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 69.0
The remainder is 13 after subtracting 441 from 454.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 49

Let's proceed to step 5:
When dividing 135 by 49, we get 2 with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 692.0
Subtracting 98 from 135 leaves us with 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 49

Step 6:
The number 49 fits into 377 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 6927.0
The remainder is 34 after subtracting 343 from 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
If we divide 340 by 49, we get 6 and a remainder of 46.
The number 6 becomes the next digit in our result. 
Result so far: 6927.6
Subtracting 294 from 340 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 8:
When dividing 460 by 49, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 6927.69
If we subtract 441 from 460, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 9:
49 goes into 190 3 times with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 6927.693
The remainder is 43 after subtracting 147 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 10:
49 goes into 430 8 times with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 6927.6938
Deduct 392 from 430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 11:
If we divide 380 by 49, we get 7 and a remainder of 37.
The number 7 becomes the next digit in our result. 
Result so far: 6927.69387
Subtracting 343 from 380 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 12:
49 goes into 370 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 6927.693877
The remainder is 27 after subtracting 343 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 6927.693877, with a leftover of 2.7e-06.
