We look at the division of 290393 by 49 
The aim is to understand the frequency of 49 in 290393.

Step 1:
2 divided by 49 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 49

Let's proceed to step 2:
If we divide 29 by 49, we get 0 and a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Append the next digit (0) from the dividend to 29 and continue with: 290 / 49

Let's proceed to step 3:
49 goes into 290 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 245 from 290, we get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 49

Step 4:
453 divided by 49 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 59.0
Subtract 441 from 453 to get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 49

Moving on to step 5:
49 goes into 129 2 times with a remainder of 31.
The next digit of our result is 2. 
Result so far: 592.0
If we take 98 away from 129, we end up with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 49

Step 6:
49 can be fit into 313 6 times, resulting in a remainder of 19.
The next digit of our result is 6. 
Result so far: 5926.0
If we take 294 away from 313, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
The number 49 fits into 190 3 times, leaving a remainder of 43.
The next digit of our result is 3. 
Result so far: 5926.3
Subtracting 147 from 190 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 8:
When dividing 430 by 49, we get 8 with a remainder of 38.
Record the quotient 8 as the next digit in the result. 
Result so far: 5926.38
Subtract 392 from 430 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
The number 49 fits into 380 7 times, leaving a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 5926.387
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.

Let's proceed to step 10:
49 goes into 370 7 times with a remainder of 27.
The next digit of our result is 7. 
Result so far: 5926.3877
If we take 343 away from 370, we end up with 27.
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 5926.3877, with a leftover of 0.00027.
