768968 divided by 50 
The aim is to understand the frequency of 50 in 768968.

On to step 1:
7 divided by 50 is 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 50

Advancing to step 2:
The number 50 fits into 76 1 times, leaving a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 26 after subtracting 50 from 76.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 50

On to step 3:
The number 50 fits into 268 5 times, leaving a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we subtract 250 from 268, we get 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 50

Advancing to step 4:
50 goes into 189 3 times with a remainder of 39.
Use 3 as the next digit of our solution. 
Result so far: 153.0
The remainder is 39 after subtracting 150 from 189.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 50

On to step 5:
50 goes into 396 7 times with a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 1537.0
Subtracting 350 from 396 leaves us with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 50

Let's proceed to step 6:
468 divided by 50 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 15379.0
If we subtract 450 from 468, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
180 divided by 50 is 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 15379.3
If we take 150 away from 180, we end up 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.

On to step 8:
300 divided by 50 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 15379.36
If we take 300 away from 300, 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.

Let's proceed to step 9:
When dividing 0 by 50, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15379.36
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.

Let's proceed to step 10:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15379.36
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.

After the division, we end up with 15379.36 and a remainder of 0.0.
