We're dividing 781458 by 50 
The aim is to understand the frequency of 50 in 781458.

Let's proceed to step 1:
The number 50 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 50

Let's proceed to step 2:
50 can be fit into 78 1 times, resulting in a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 50 away from 78, we end up with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 50

Moving on to step 3:
50 can be fit into 281 5 times, resulting in a remainder of 31.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 250 from 281, we get 31.
Grab the next digit (4) from the dividend, add it to 31, then carry on: 314 / 50

Let's proceed to step 4:
50 can be fit into 314 6 times, resulting in a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 156.0
The remainder is 14 after subtracting 300 from 314.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 50

Moving on to step 5:
50 can be fit into 145 2 times, resulting in a remainder of 45.
The next digit of our result is 2. 
Result so far: 1562.0
If we subtract 100 from 145, we get 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 50

Advancing to step 6:
50 goes into 458 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 15629.0
Deduct 450 from 458 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
If we divide 80 by 50, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 15629.1
Deduct 50 from 80 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
50 goes into 300 6 times with a remainder of 0.
The next digit of our result is 6. 
Result so far: 15629.16
Subtract 300 from 300 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:
50 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15629.16
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.

Advancing to step 10:
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: 15629.16
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.

In conclusion, the division gives 15629.16 with a balance of 0.0.
