778799 divided by 50 
The aim is to understand the frequency of 50 in 778799.

Moving on to step 1:
When dividing 7 by 50, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 50

On to step 2:
50 goes into 77 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 50 from 77 leaves us with 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 50

On to step 3:
If we divide 278 by 50, we get 5 and a remainder of 28.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Deduct 250 from 278 and we're left with 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 50

Advancing to step 4:
The number 50 fits into 287 5 times, leaving a remainder of 37.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Deduct 250 from 287 and we're left with 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 50

Advancing to step 5:
If we divide 379 by 50, we get 7 and a remainder of 29.
Record the quotient 7 as the next digit in the result. 
Result so far: 1557.0
If we take 350 away from 379, we end up with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 50

Advancing to step 6:
50 can be fit into 299 5 times, resulting in a remainder of 49.
The next digit of our result is 5. 
Result so far: 15575.0
If we subtract 250 from 299, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
490 divided by 50 is 9 with a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 15575.9
The remainder is 40 after subtracting 450 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
400 divided by 50 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 15575.98
Deduct 400 from 400 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.

Step 9:
0 divided by 50 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15575.98
Subtract 0 from 0 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.

Advancing to step 10:
When dividing 0 by 50, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15575.98
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.

Our division results in 15575.98 with a remaining 0.0.
