We look at the division of 892603 by 80 
The aim is to understand the frequency of 80 in 892603.

On to step 1:
If we divide 8 by 80, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 80

On to step 2:
80 goes into 89 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we take 80 away from 89, we end up with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 80

Step 3:
92 divided by 80 is 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtracting 80 from 92 leaves us with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 80

On to step 4:
80 goes into 126 1 times with a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 111.0
The remainder is 46 after subtracting 80 from 126.
Grab the next digit (0) from the dividend, add it to 46, then carry on: 460 / 80

On to step 5:
80 goes into 460 5 times with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 1115.0
The remainder is 60 after subtracting 400 from 460.
Take the next digit (3) from the dividend and append it to 60, then repeat: 603 / 80

On to step 6:
The number 80 fits into 603 7 times, leaving a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 11157.0
If we take 560 away from 603, we end up with 43.
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:
If we divide 430 by 80, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11157.5
Subtract 400 from 430 to 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.

Moving on to step 8:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 11157.53
If we take 240 away from 300, we end up 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.

Going ahead to step 9:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 11157.537
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.

Moving on to step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11157.5375
The remainder is 0 after subtracting 400 from 400.
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:
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: 11157.5375
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.

Going ahead to step 12:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11157.5375
If we take 0 away from 0, 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.

Our division results in 11157.5375 with a remaining 0.0.
