We divide 839396 by 80
The aim is to understand the frequency of 80 in 839396.

Going ahead to step 1:
80 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 80

Moving on to step 2:
83 divided by 80 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 80 away from 83, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 80

Moving on to step 3:
The number 80 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 39, we get 39.
Grab the next digit (3) from the dividend, add it to 39, then carry on: 393 / 80

Let's proceed to step 4:
80 goes into 393 4 times with a remainder of 73.
Write down 4 as next digit of the result. 
Result so far: 104.0
Deduct 320 from 393 and we're left with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 80

Going ahead to step 5:
739 divided by 80 is 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 1049.0
The remainder is 19 after subtracting 720 from 739.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 80

Let's proceed to step 6:
80 goes into 196 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 10492.0
Subtracting 160 from 196 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
80 can be fit into 360 4 times, resulting in a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 10492.4
The remainder is 40 after subtracting 320 from 360.
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 8:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 10492.45
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 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10492.45
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 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10492.45
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.

After the division, we end up with 10492.45 and a remainder of 0.0.
