We're dividing 702790 by 50 
The aim is to understand the frequency of 50 in 702790.

Moving on to step 1:
50 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 50

Moving on to step 2:
When dividing 70 by 50, we get 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 50 from 70 and we're left with 20.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 50

Advancing to step 3:
The number 50 fits into 202 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Subtract 200 from 202 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 50

Let's proceed to step 4:
50 goes into 27 0 times with a remainder of 27.
The next digit of our result is 0. 
Result so far: 140.0
The remainder is 27 after subtracting 0 from 27.
Include the next digit (9) from the dividend after 27, then repeat: 279 / 50

Step 5:
279 divided by 50 is 5 with a remainder of 29.
Record the quotient 5 as the next digit in the result. 
Result so far: 1405.0
Deduct 250 from 279 and we're left with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 50

Advancing to step 6:
The number 50 fits into 290 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 14055.0
If we take 250 away from 290, we end up 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.

On to step 7:
If we divide 400 by 50, we get 8 and a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 14055.8
Subtract 400 from 400 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.

On to step 8:
50 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14055.8
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.

On to step 9:
50 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14055.8
The remainder is 0 after subtracting 0 from 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 14055.8 with a remaining 0.0.
