80718695 ÷ 50 
The aim is to understand the frequency of 50 in 80718695.

Going ahead to step 1:
If we divide 8 by 50, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 50

Advancing to step 2:
80 divided by 50 is 1 with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 50 from 80 leaves us with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 50

Moving on to step 3:
When dividing 307 by 50, we get 6 with a remainder of 7.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 300 away from 307, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 50

On to step 4:
When dividing 71 by 50, we get 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 161.0
Deduct 50 from 71 and we're left with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 50

Moving on to step 5:
If we divide 218 by 50, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 1614.0
Subtracting 200 from 218 leaves us with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 50

Advancing to step 6:
50 can be fit into 186 3 times, resulting in a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 16143.0
The remainder is 36 after subtracting 150 from 186.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 50

Advancing to step 7:
50 can be fit into 369 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 161437.0
If we subtract 350 from 369, we get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 50

Let's proceed to step 8:
50 goes into 195 3 times with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 1614373.0
Subtract 150 from 195 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 9:
If we divide 450 by 50, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 1614373.9
If we take 450 away from 450, 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 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: 1614373.9
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.

Moving on to step 11:
The number 50 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1614373.9
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.

After the division, we end up with 1614373.9 and a remainder of 0.0.
