621062 ÷ 50 
The aim is to understand the frequency of 50 in 621062.

Step 1:
The number 50 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 50

Step 2:
50 goes into 62 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 12 after subtracting 50 from 62.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 50

On to step 3:
The number 50 fits into 121 2 times, leaving a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 100 from 121 and we're left with 21.
Include the next digit (0) from the dividend after 21, then repeat: 210 / 50

Moving on to step 4:
When dividing 210 by 50, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 124.0
If we subtract 200 from 210, we get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 50

Step 5:
50 goes into 106 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1242.0
If we subtract 100 from 106, we get 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 50

Going ahead to step 6:
The number 50 fits into 62 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 12421.0
Deduct 50 from 62 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
When dividing 120 by 50, we get 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 12421.2
Deduct 100 from 120 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 50 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 12421.24
Deduct 200 from 200 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.

Step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12421.24
If we subtract 0 from 0, we 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.

Moving on to step 10:
When dividing 0 by 50, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12421.24
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.

The quotient of the division is 12421.24, and the remainder is 0.0.
