We divide 73554 by 80
The aim is to understand the frequency of 80 in 73554.

Moving on to step 1:
7 divided by 80 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 80

Step 2:
80 can be fit into 73 0 times, resulting in a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 73 after subtracting 0 from 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 80

Advancing to step 3:
80 can be fit into 735 9 times, resulting in a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 720 from 735 to get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 80

Moving on to step 4:
If we divide 155 by 80, we get 1 and a remainder of 75.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we take 80 away from 155, we end up with 75.
Append the next digit (4) from the dividend to 75 and continue with: 754 / 80

Step 5:
754 divided by 80 is 9 with a remainder of 34.
Record the quotient 9 as the next digit in the result. 
Result so far: 919.0
The remainder is 34 after subtracting 720 from 754.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 6:
When dividing 340 by 80, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 919.4
The remainder is 20 after subtracting 320 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
200 divided by 80 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 919.42
If we subtract 160 from 200, we 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 8:
80 goes into 400 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 919.425
The remainder is 0 after subtracting 400 from 400.
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:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 919.425
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.

Step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 919.425
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 919.425 with a remainder of 0.0.
