We look at the division of 320620 by 50 
The aim is to understand the frequency of 50 in 320620.

Going ahead to step 1:
50 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 50

Step 2:
If we divide 32 by 50, we get 0 and a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Grab the next digit (0) from the dividend, add it to 32, then carry on: 320 / 50

Going ahead to step 3:
The number 50 fits into 320 6 times, leaving a remainder of 20.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 300 from 320 leaves us with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 50

Advancing to step 4:
50 can be fit into 206 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 64.0
The remainder is 6 after subtracting 200 from 206.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 50

On to step 5:
The number 50 fits into 62 1 times, leaving a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 641.0
If we take 50 away from 62, we end up with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 50

Let's proceed to step 6:
50 goes into 120 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 6412.0
Subtracting 100 from 120 leaves us 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.

Let's proceed to step 7:
If we divide 200 by 50, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 6412.4
Subtracting 200 from 200 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.

Advancing to step 8:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6412.4
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.

Going ahead to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6412.4
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.

The quotient of the division is 6412.4, and the remainder is 0.0.
