Let's divide 510821 by 50
The aim is to understand the frequency of 50 in 510821.

Going ahead to step 1:
50 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 50

On to step 2:
50 can be fit into 51 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 50 from 51 and we're left with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 50

On to step 3:
50 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 10 to get 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 50

Going ahead to step 4:
50 can be fit into 108 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
The remainder is 8 after subtracting 100 from 108.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 50

Let's proceed to step 5:
The number 50 fits into 82 1 times, leaving a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1021.0
Deduct 50 from 82 and we're left with 32.
Include the next digit (1) from the dividend after 32, then repeat: 321 / 50

Let's proceed to step 6:
When dividing 321 by 50, we get 6 with a remainder of 21.
The next digit of our result is 6. 
Result so far: 10216.0
The remainder is 21 after subtracting 300 from 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to 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: 10216.4
If we subtract 200 from 210, we 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.

On to step 8:
If we divide 100 by 50, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 10216.42
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.

Let's proceed to step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10216.42
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.

Moving on to step 10:
If we divide 0 by 50, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10216.42
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.

Our division results in 10216.42 with a remaining 0.0.
