We divide 958043 by 80
The aim is to understand the frequency of 80 in 958043.

Advancing to step 1:
9 divided by 80 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 80

Moving on to step 2:
When dividing 95 by 80, we get 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 80 from 95, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 80

Moving on to step 3:
The number 80 fits into 158 1 times, leaving a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 80 from 158 to get 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 80

Step 4:
The number 80 fits into 780 9 times, leaving a remainder of 60.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Deduct 720 from 780 and we're left with 60.
Include the next digit (4) from the dividend after 60, then repeat: 604 / 80

Advancing to step 5:
If we divide 604 by 80, we get 7 and a remainder of 44.
Record the quotient 7 as the next digit in the result. 
Result so far: 1197.0
If we take 560 away from 604, we end up with 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 80

Moving on to step 6:
443 divided by 80 is 5 with a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 11975.0
The remainder is 43 after subtracting 400 from 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 7:
When dividing 430 by 80, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11975.5
If we subtract 400 from 430, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
The number 80 fits into 300 3 times, leaving a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 11975.53
Deduct 240 from 300 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.

Advancing to step 9:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 11975.537
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11975.5375
Subtracting 400 from 400 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.

Going ahead to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11975.5375
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.

Step 12:
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: 11975.5375
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.

The final result is 11975.5375 with a remainder of 0.0.
