Let's divide 20359 by 50
The aim is to understand the frequency of 50 in 20359.

Advancing to step 1:
When dividing 2 by 50, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 50

Going ahead to step 2:
The number 50 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 50

Moving on to step 3:
If we divide 203 by 50, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 200 from 203 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 50

Moving on to step 4:
If we divide 35 by 50, we get 0 and a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtracting 0 from 35 leaves us with 35.
Fetch the next digit (9) from the dividend, attach it to 35 and continue: 359 / 50

On to step 5:
The number 50 fits into 359 7 times, leaving a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 407.0
The remainder is 9 after subtracting 350 from 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 6:
The number 50 fits into 90 1 times, leaving a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 407.1
If we take 50 away from 90, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
If we divide 400 by 50, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 407.18
If we subtract 400 from 400, 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:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 407.18
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.

Advancing 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: 407.18
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.

Our division results in 407.18 with a remaining 0.0.
