We divide 620545 by 50
The aim is to understand the frequency of 50 in 620545.

Advancing to step 1:
If we divide 6 by 50, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 50

Moving on to step 2:
The number 50 fits into 62 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 50 from 62, we get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 50

On to step 3:
120 divided by 50 is 2 with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtracting 100 from 120 leaves us with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 50

On to step 4:
205 divided by 50 is 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
If we subtract 200 from 205, we get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 50

Advancing to step 5:
54 divided by 50 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1241.0
Deduct 50 from 54 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 50

Going ahead to step 6:
The number 50 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 12410.0
If we subtract 0 from 45, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
50 can be fit into 450 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 12410.9
If we subtract 450 from 450, 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.

On to step 8:
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: 12410.9
Subtracting 0 from 0 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.

Let's proceed to step 9:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12410.9
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.

In conclusion, the division gives 12410.9 with a balance of 0.0.
