Let's divide 803499 by 80
The aim is to understand the frequency of 80 in 803499.

Going ahead to step 1:
When dividing 8 by 80, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 80

Moving on to step 2:
80 divided by 80 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 80 from 80.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 80

Let's proceed to step 3:
80 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 3, we end up with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 80

Let's proceed to step 4:
80 goes into 34 0 times with a remainder of 34.
Write down 0 as next digit of the result. 
Result so far: 100.0
Subtract 0 from 34 to get 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 80

Advancing to step 5:
The number 80 fits into 349 4 times, leaving a remainder of 29.
Record the quotient 4 as the next digit in the result. 
Result so far: 1004.0
Subtract 320 from 349 to get 29.
Include the next digit (9) from the dividend after 29, then repeat: 299 / 80

Advancing to step 6:
80 can be fit into 299 3 times, resulting in a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 10043.0
Subtracting 240 from 299 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
When dividing 590 by 80, we get 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 10043.7
If we take 560 away from 590, 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.

Moving on to step 8:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 10043.73
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.

Moving on to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 10043.737
If we take 560 away from 600, 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.

Going ahead to step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10043.7375
Deduct 400 from 400 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.

Advancing to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 10043.7375
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.

Going ahead to step 12:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10043.7375
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 quotient of the division is 10043.7375, and the remainder is 0.0.
