We divide 1243394 by 80
The aim is to understand the frequency of 80 in 1243394.

Moving on to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 80

On to step 2:
When dividing 12 by 80, we get 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 80

Going ahead to step 3:
124 divided by 80 is 1 with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 80 from 124 to get 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 80

Advancing to step 4:
When dividing 443 by 80, we get 5 with a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 15.0
The remainder is 43 after subtracting 400 from 443.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 80

Advancing to step 5:
When dividing 433 by 80, we get 5 with a remainder of 33.
Put 5 as the next digit of the answer. 
Result so far: 155.0
Subtracting 400 from 433 leaves us with 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 80

Moving on to step 6:
If we divide 339 by 80, we get 4 and a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 1554.0
Subtracting 320 from 339 leaves us with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 80

Moving on to step 7:
The number 80 fits into 194 2 times, leaving a remainder of 34.
The next digit of our result is 2. 
Result so far: 15542.0
Subtract 160 from 194 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
If we divide 340 by 80, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 15542.4
Subtract 320 from 340 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
When dividing 200 by 80, we get 2 with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 15542.42
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.

Moving on to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15542.425
If we take 400 away from 400, we end up 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 11:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15542.425
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:
If we divide 0 by 80, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15542.425
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.

In conclusion, the division gives 15542.425 with a balance of 0.0.
