787860 divided by 50 
The aim is to understand the frequency of 50 in 787860.

On to step 1:
When dividing 7 by 50, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 50

On to step 2:
50 can be fit into 78 1 times, resulting in a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 50 from 78 and we're left with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 50

Going ahead to step 3:
If we divide 287 by 50, we get 5 and a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 250 from 287, we get 37.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 50

Moving on to step 4:
When dividing 378 by 50, we get 7 with a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 157.0
If we take 350 away from 378, we end up with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 50

Moving on to step 5:
When dividing 286 by 50, we get 5 with a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 1575.0
Deduct 250 from 286 and we're left with 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 50

Let's proceed to step 6:
50 goes into 360 7 times with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 15757.0
Subtracting 350 from 360 leaves us 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.

Let's proceed to step 7:
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: 15757.2
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 8:
50 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15757.2
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.

On to step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15757.2
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.

In conclusion, the division gives 15757.2 with a balance of 0.0.
