We're dividing 145331 by 50 
The aim is to understand the frequency of 50 in 145331.

Step 1:
1 divided by 50 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 50

Moving on to step 2:
14 divided by 50 is 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 50

Advancing to step 3:
50 goes into 145 2 times with a remainder of 45.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 100 from 145 and we're left with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 50

On to step 4:
50 goes into 453 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Deduct 450 from 453 and we're left with 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 50

Going ahead to step 5:
50 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 290.0
Subtract 0 from 33 to get 33.
Append the next digit (1) from the dividend to 33 and continue with: 331 / 50

Let's proceed to step 6:
50 can be fit into 331 6 times, resulting in a remainder of 31.
The next digit of our result is 6. 
Result so far: 2906.0
The remainder is 31 after subtracting 300 from 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
50 can be fit into 310 6 times, resulting in a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 2906.6
The remainder is 10 after subtracting 300 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
The number 50 fits into 100 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2906.62
The remainder is 0 after subtracting 100 from 100.
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:
When dividing 0 by 50, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2906.62
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.

Let's proceed to step 10:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2906.62
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.

Our division results in 2906.62 with a remaining 0.0.
