We're dividing 872271 by 50 
The aim is to understand the frequency of 50 in 872271.

Going ahead to step 1:
When dividing 8 by 50, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 50

Moving on to step 2:
If we divide 87 by 50, we get 1 and a remainder of 37.
The next digit of our result is 1. 
Result so far: 1.0
If we take 50 away from 87, we end up with 37.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 50

Let's proceed to step 3:
372 divided by 50 is 7 with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 350 from 372, we get 22.
Include the next digit (2) from the dividend after 22, then repeat: 222 / 50

Moving on to step 4:
When dividing 222 by 50, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 174.0
Deduct 200 from 222 and we're left with 22.
Include the next digit (7) from the dividend after 22, then repeat: 227 / 50

Step 5:
50 goes into 227 4 times with a remainder of 27.
Put 4 as the next digit of the answer. 
Result so far: 1744.0
Subtract 200 from 227 to get 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 50

Moving on to step 6:
50 can be fit into 271 5 times, resulting in a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 17445.0
Deduct 250 from 271 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
50 goes into 210 4 times with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 17445.4
Subtract 200 from 210 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 50, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 17445.42
Subtracting 100 from 100 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.

On to step 9:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17445.42
Subtract 0 from 0 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.

Let's proceed to step 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17445.42
Subtract 0 from 0 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.

The final outcome is 17445.42, with a leftover of 0.0.
