We're dividing 718903 by 50 
The aim is to understand the frequency of 50 in 718903.

On to step 1:
When dividing 7 by 50, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 50

Advancing to step 2:
If we divide 71 by 50, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 50 away from 71, we end up with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 50

On to step 3:
If we divide 218 by 50, we get 4 and a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtract 200 from 218 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 50

Advancing to step 4:
When dividing 189 by 50, we get 3 with a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 143.0
The remainder is 39 after subtracting 150 from 189.
Append the next digit (0) from the dividend to 39 and continue with: 390 / 50

Step 5:
50 can be fit into 390 7 times, resulting in a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 1437.0
If we subtract 350 from 390, we get 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 50

Going ahead to step 6:
50 goes into 403 8 times with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 14378.0
If we subtract 400 from 403, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
If we divide 30 by 50, we get 0 and a remainder of 30.
The next digit of our result is 0. 
Result so far: 14378.0
Subtracting 0 from 30 leaves us 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.

Step 8:
The number 50 fits into 300 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 14378.06
If we subtract 300 from 300, 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.

Going ahead to step 9:
If we divide 0 by 50, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 14378.06
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.

Let's proceed to step 10:
50 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14378.06
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.

The final outcome is 14378.06, with a leftover of 0.0.
