We're dividing 613743 by 80 
The aim is to understand the frequency of 80 in 613743.

Step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 80

Going ahead to step 2:
61 divided by 80 is 0 with a remainder of 61.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 61 leaves us with 61.
Bring next digit (3) of the dividend behind the 61 and repeat the process: 613 / 80

Let's proceed to step 3:
If we divide 613 by 80, we get 7 and a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 560 from 613 to get 53.
Grab the next digit (7) from the dividend, add it to 53, then carry on: 537 / 80

Let's proceed to step 4:
80 can be fit into 537 6 times, resulting in a remainder of 57.
The next digit of our result is 6. 
Result so far: 76.0
Deduct 480 from 537 and we're left with 57.
Bring next digit (4) of the dividend behind the 57 and repeat the process: 574 / 80

Advancing to step 5:
80 goes into 574 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 767.0
Subtract 560 from 574 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 80

Advancing to step 6:
80 can be fit into 143 1 times, resulting in a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 7671.0
Subtract 80 from 143 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
If we divide 630 by 80, we get 7 and a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 7671.7
Subtracting 560 from 630 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 8:
80 can be fit into 700 8 times, resulting in a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 7671.78
Deduct 640 from 700 and we're left with 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:
80 goes into 600 7 times with a remainder of 40.
The next digit of our result is 7. 
Result so far: 7671.787
Subtracting 560 from 600 leaves us 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.

Moving on to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7671.7875
Subtract 400 from 400 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.

Advancing to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7671.7875
If we subtract 0 from 0, 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.

Advancing to step 12:
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: 7671.7875
If we subtract 0 from 0, 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.

In conclusion, the division gives 7671.7875 with a balance of 0.0.
