172153 ÷ 50 
The aim is to understand the frequency of 50 in 172153.

Advancing to step 1:
50 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 50

Moving on to step 2:
When dividing 17 by 50, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 50

Moving on to step 3:
When dividing 172 by 50, we get 3 with a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 150 from 172 to get 22.
Grab the next digit (1) from the dividend, add it to 22, then carry on: 221 / 50

Step 4:
If we divide 221 by 50, we get 4 and a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 34.0
If we subtract 200 from 221, we get 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 50

On to step 5:
215 divided by 50 is 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 344.0
If we subtract 200 from 215, we get 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 50

On to step 6:
The number 50 fits into 153 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 3443.0
The remainder is 3 after subtracting 150 from 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
When dividing 30 by 50, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 3443.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 50 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 3443.06
Subtracting 300 from 300 leaves us 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.

Moving on to step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3443.06
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.

Going ahead to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3443.06
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.

The final result is 3443.06 with a remainder of 0.0.
