Let's divide 21728252 by 50
The aim is to understand the frequency of 50 in 21728252.

Moving on to step 1:
When dividing 2 by 50, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 50

Moving on to step 2:
21 divided by 50 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 50

On to step 3:
If we divide 217 by 50, we get 4 and a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 200 from 217, we get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 50

Going ahead to step 4:
50 can be fit into 172 3 times, resulting in a remainder of 22.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we subtract 150 from 172, we get 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 50

Moving on to step 5:
The number 50 fits into 228 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 434.0
The remainder is 28 after subtracting 200 from 228.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 50

On to step 6:
50 goes into 282 5 times with a remainder of 32.
Use 5 as the next digit of our solution. 
Result so far: 4345.0
If we take 250 away from 282, we end up with 32.
Take the next digit (5) from the dividend and append it to 32, then repeat: 325 / 50

Going ahead to step 7:
If we divide 325 by 50, we get 6 and a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 43456.0
Deduct 300 from 325 and we're left with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 50

On to step 8:
When dividing 252 by 50, we get 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 434565.0
Subtract 250 from 252 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
50 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 434565.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
The number 50 fits into 200 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 434565.04
If we take 200 away from 200, we end up 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.

Going ahead to step 11:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 434565.04
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.

Moving on to step 12:
0 divided by 50 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 434565.04
If we take 0 away from 0, we end up 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.

After the division, we end up with 434565.04 and a remainder of 0.0.
