279949 ÷ 50 
The aim is to understand the frequency of 50 in 279949.

Advancing to step 1:
The number 50 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 50

Moving on to step 2:
27 divided by 50 is 0 with a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 50

Let's proceed to step 3:
If we divide 279 by 50, we get 5 and a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 250 away from 279, we end up with 29.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 50

Step 4:
50 can be fit into 299 5 times, resulting in a remainder of 49.
Write down 5 as next digit of the result. 
Result so far: 55.0
Subtracting 250 from 299 leaves us with 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 50

Step 5:
The number 50 fits into 494 9 times, leaving a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 559.0
Deduct 450 from 494 and we're left with 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 50

Step 6:
50 goes into 449 8 times with a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 5598.0
Subtract 400 from 449 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 7:
If we divide 490 by 50, we get 9 and a remainder of 40.
Put 9 as the next digit of the answer. 
Result so far: 5598.9
Subtract 450 from 490 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 50 fits into 400 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 5598.98
Subtract 400 from 400 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 5598.98
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5598.98
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 5598.98 with a remaining 0.0.
