We divide 173976 by 80
The aim is to understand the frequency of 80 in 173976.

Moving on to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 80

Going ahead to step 2:
If we divide 17 by 80, we get 0 and a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 80

Step 3:
The number 80 fits into 173 2 times, leaving a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 13 after subtracting 160 from 173.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 80

On to step 4:
80 can be fit into 139 1 times, resulting in a remainder of 59.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
The remainder is 59 after subtracting 80 from 139.
Append the next digit (7) from the dividend to 59 and continue with: 597 / 80

Step 5:
80 goes into 597 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 217.0
Subtract 560 from 597 to get 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 80

Going ahead to step 6:
80 goes into 376 4 times with a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 2174.0
Subtracting 320 from 376 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
The number 80 fits into 560 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 2174.7
Subtracting 560 from 560 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.

Moving on to step 8:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 2174.7
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.

Let's proceed to step 9:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 2174.7
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 quotient of the division is 2174.7, and the remainder is 0.0.
