673384 ÷ 80 
The aim is to understand the frequency of 80 in 673384.

On to step 1:
80 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 80

Moving on to step 2:
80 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 80

Let's proceed to step 3:
If we divide 673 by 80, we get 8 and a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 640 from 673, we get 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 80

Going ahead to step 4:
333 divided by 80 is 4 with a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtracting 320 from 333 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 80

On to step 5:
138 divided by 80 is 1 with a remainder of 58.
The next digit of our result is 1. 
Result so far: 841.0
Deduct 80 from 138 and we're left with 58.
Fetch the next digit (4) from the dividend, attach it to 58 and continue: 584 / 80

Moving on to step 6:
If we divide 584 by 80, we get 7 and a remainder of 24.
The next digit of our result is 7. 
Result so far: 8417.0
If we subtract 560 from 584, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
240 divided by 80 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 8417.3
Subtracting 240 from 240 leaves us 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 8:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8417.3
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.

On to step 9:
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: 8417.3
Subtracting 0 from 0 leaves us 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.

The final result is 8417.3 with a remainder of 0.0.
