We look at the division of 1577850 by 50 
The aim is to understand the frequency of 50 in 1577850.

Moving on to step 1:
50 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 50

Let's proceed to step 2:
If we divide 15 by 50, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (7) from the dividend, add it to 15, then carry on: 157 / 50

Let's proceed to step 3:
157 divided by 50 is 3 with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 150 away from 157, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 50

Moving on to step 4:
The number 50 fits into 77 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 50 from 77 to get 27.
Include the next digit (8) from the dividend after 27, then repeat: 278 / 50

Moving on to step 5:
When dividing 278 by 50, we get 5 with a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 315.0
Subtracting 250 from 278 leaves us with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 50

Going ahead to step 6:
When dividing 285 by 50, we get 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 3155.0
If we subtract 250 from 285, we get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 50

On to step 7:
50 goes into 350 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 31557.0
Subtracting 350 from 350 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.

Step 8:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31557.0
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.

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: 31557.0
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 final outcome is 31557.0, with a leftover of 0.0.
