We're dividing 771731 by 50 
The aim is to understand the frequency of 50 in 771731.

Going ahead to step 1:
If we divide 7 by 50, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 50

On to step 2:
50 can be fit into 77 1 times, resulting in a remainder of 27.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 50 from 77 and we're left with 27.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 50

Let's proceed to step 3:
The number 50 fits into 271 5 times, leaving a remainder of 21.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 250 from 271, we get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 50

Moving on to step 4:
When dividing 217 by 50, we get 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 154.0
If we take 200 away from 217, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 50

On to step 5:
50 goes into 173 3 times with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 1543.0
If we subtract 150 from 173, we get 23.
Take the next digit (1) from the dividend and append it to 23, then repeat: 231 / 50

Advancing to step 6:
When dividing 231 by 50, we get 4 with a remainder of 31.
Record the quotient 4 as the next digit in the result. 
Result so far: 15434.0
The remainder is 31 after subtracting 200 from 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
50 goes into 310 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 15434.6
If we take 300 away from 310, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
When dividing 100 by 50, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 15434.62
Subtract 100 from 100 to 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.

Moving on to step 9:
0 divided by 50 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15434.62
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.

Advancing to step 10:
50 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15434.62
If we take 0 away from 0, 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.

Our division results in 15434.62 with a remaining 0.0.
