786354 ÷ 50 
The aim is to understand the frequency of 50 in 786354.

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
If we subtract 0 from 7, we get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 50

Moving on to step 2:
The number 50 fits into 78 1 times, leaving a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 50 from 78 to get 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 50

Step 3:
50 goes into 286 5 times with a remainder of 36.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 250 from 286, we get 36.
Take the next digit (3) from the dividend and append it to 36, then repeat: 363 / 50

Let's proceed to step 4:
50 can be fit into 363 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 157.0
If we take 350 away from 363, we end up with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 50

Moving on to step 5:
If we divide 135 by 50, we get 2 and a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 1572.0
The remainder is 35 after subtracting 100 from 135.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 50

On to step 6:
50 goes into 354 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 15727.0
If we take 350 away from 354, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
50 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 15727.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 50 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 15727.08
The remainder is 0 after subtracting 400 from 400.
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:
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: 15727.08
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.

Step 10:
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: 15727.08
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.

After the division, we end up with 15727.08 and a remainder of 0.0.
