721056 ÷ 50 
The aim is to understand the frequency of 50 in 721056.

Going ahead to step 1:
If we divide 7 by 50, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 50

On to step 2:
50 can be fit into 72 1 times, resulting in a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 50 from 72 leaves us with 22.
Bring next digit (1) of the dividend behind the 22 and repeat the process: 221 / 50

Step 3:
50 can be fit into 221 4 times, resulting in a remainder of 21.
The next digit of our result is 4. 
Result so far: 14.0
If we take 200 away from 221, we end up with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 50

Advancing to step 4:
The number 50 fits into 210 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 144.0
The remainder is 10 after subtracting 200 from 210.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 50

Going ahead to step 5:
105 divided by 50 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 1442.0
Subtracting 100 from 105 leaves us with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 50

Moving on to step 6:
56 divided by 50 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 14421.0
The remainder is 6 after subtracting 50 from 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 50 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 14421.1
The remainder is 10 after subtracting 50 from 60.
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:
50 goes into 100 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 14421.12
The remainder is 0 after subtracting 100 from 100.
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:
0 divided by 50 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14421.12
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.

On to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14421.12
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 14421.12 with a remainder of 0.0.
