788987 ÷ 50 
The aim is to understand the frequency of 50 in 788987.

Let's proceed to step 1:
7 divided by 50 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 50

Step 2:
50 goes into 78 1 times with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 28 after subtracting 50 from 78.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 50

Let's proceed to step 3:
When dividing 288 by 50, we get 5 with a remainder of 38.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 250 from 288 leaves us with 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 50

Moving on to step 4:
If we divide 389 by 50, we get 7 and a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
Deduct 350 from 389 and we're left with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 50

Going ahead to step 5:
50 can be fit into 398 7 times, resulting in a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 1577.0
Deduct 350 from 398 and we're left with 48.
Bring next digit (7) of the dividend behind the 48 and repeat the process: 487 / 50

Step 6:
50 goes into 487 9 times with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 15779.0
If we take 450 away from 487, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
The number 50 fits into 370 7 times, leaving a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 15779.7
The remainder is 20 after subtracting 350 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
50 can be fit into 200 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 15779.74
Subtract 200 from 200 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.

Let's proceed 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: 15779.74
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.

Advancing to step 10:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15779.74
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 15779.74, with a leftover of 0.0.
