731835 divided by 80 
The aim is to understand the frequency of 80 in 731835.

Step 1:
80 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 80

Step 2:
The number 80 fits into 73 0 times, leaving a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 73, we get 73.
Append the next digit (1) from the dividend to 73 and continue with: 731 / 80

Step 3:
80 goes into 731 9 times with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 720 from 731 leaves us with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 80

Advancing to step 4:
The number 80 fits into 118 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we take 80 away from 118, we end up with 38.
Grab the next digit (3) from the dividend, add it to 38, then carry on: 383 / 80

Advancing to step 5:
80 can be fit into 383 4 times, resulting in a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 914.0
If we take 320 away from 383, we end up with 63.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 80

Let's proceed to step 6:
When dividing 635 by 80, we get 7 with a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 9147.0
Subtract 560 from 635 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 7:
80 can be fit into 750 9 times, resulting in a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 9147.9
If we take 720 away from 750, 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.

Step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
The next digit of our result is 3. 
Result so far: 9147.93
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
80 goes into 600 7 times with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 9147.937
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9147.9375
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 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9147.9375
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.

Let's proceed to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9147.9375
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.

The final result is 9147.9375 with a remainder of 0.0.
