We're dividing 735039 by 80 
The aim is to understand the frequency of 80 in 735039.

Going ahead to step 1:
80 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 80

Moving on to step 2:
The number 80 fits into 73 0 times, leaving a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Bring next digit (5) of the dividend behind the 73 and repeat the process: 735 / 80

Step 3:
When dividing 735 by 80, we get 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 720 from 735 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 80

Let's proceed to step 4:
80 can be fit into 150 1 times, resulting in a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Deduct 80 from 150 and we're left with 70.
Fetch the next digit (3) from the dividend, attach it to 70 and continue: 703 / 80

Going ahead to step 5:
If we divide 703 by 80, we get 8 and a remainder of 63.
Put 8 as the next digit of the answer. 
Result so far: 918.0
Subtracting 640 from 703 leaves us with 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 80

On to step 6:
If we divide 639 by 80, we get 7 and a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 9187.0
Deduct 560 from 639 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 7:
When dividing 790 by 80, we get 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 9187.9
Subtract 720 from 790 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
80 can be fit into 700 8 times, resulting in a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 9187.98
If we subtract 640 from 700, we 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:
600 divided by 80 is 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 9187.987
Deduct 560 from 600 and we're left 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.

On to step 10:
400 divided by 80 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9187.9875
If we subtract 400 from 400, 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.

Step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9187.9875
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 12:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9187.9875
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 final outcome is 9187.9875, with a leftover of 0.0.
