We look at the division of 428805 by 50 
The aim is to understand the frequency of 50 in 428805.

Let's proceed to step 1:
4 divided by 50 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 50

Advancing to step 2:
If we divide 42 by 50, we get 0 and a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Include the next digit (8) from the dividend after 42, then repeat: 428 / 50

Advancing to step 3:
50 goes into 428 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 400 from 428, we get 28.
Include the next digit (8) from the dividend after 28, then repeat: 288 / 50

Let's proceed to step 4:
If we divide 288 by 50, we get 5 and a remainder of 38.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Subtract 250 from 288 to get 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 50

Advancing to step 5:
50 can be fit into 380 7 times, resulting in a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 857.0
Subtract 350 from 380 to get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 50

Advancing to step 6:
305 divided by 50 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 8576.0
Subtracting 300 from 305 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
When dividing 50 by 50, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 8576.1
If we take 50 away from 50, 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.

Let's proceed 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: 8576.1
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.

Moving on to step 9:
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: 8576.1
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.

The quotient of the division is 8576.1, and the remainder is 0.0.
