We divide 431669 by 50
The aim is to understand the frequency of 50 in 431669.

Going ahead to step 1:
When dividing 4 by 50, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 50

Let's proceed to step 2:
When dividing 43 by 50, we get 0 with a remainder of 43.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Fetch the next digit (1) from the dividend, attach it to 43 and continue: 431 / 50

On to step 3:
The number 50 fits into 431 8 times, leaving a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 400 from 431 and we're left with 31.
Include the next digit (6) from the dividend after 31, then repeat: 316 / 50

Moving on to step 4:
If we divide 316 by 50, we get 6 and a remainder of 16.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 300 from 316 leaves us with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 50

Advancing to step 5:
50 can be fit into 166 3 times, resulting in a remainder of 16.
The next digit of our result is 3. 
Result so far: 863.0
Subtract 150 from 166 to get 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 50

Going ahead to step 6:
50 can be fit into 169 3 times, resulting in a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 8633.0
Deduct 150 from 169 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
When dividing 190 by 50, we get 3 with a remainder of 40.
The number 3 becomes the next digit in our result. 
Result so far: 8633.3
If we take 150 away from 190, 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.

On to step 8:
If we divide 400 by 50, we get 8 and a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 8633.38
If we take 400 away from 400, 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.

Going ahead to step 9:
0 divided by 50 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8633.38
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.

Advancing to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8633.38
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.

The quotient of the division is 8633.38, and the remainder is 0.0.
