785325 ÷ 80 
The aim is to understand the frequency of 80 in 785325.

Let's proceed to step 1:
80 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 80

Let's proceed to step 2:
80 can be fit into 78 0 times, resulting in a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Grab the next digit (5) from the dividend, add it to 78, then carry on: 785 / 80

On to step 3:
The number 80 fits into 785 9 times, leaving a remainder of 65.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 720 from 785 leaves us with 65.
Fetch the next digit (3) from the dividend, attach it to 65 and continue: 653 / 80

Let's proceed to step 4:
653 divided by 80 is 8 with a remainder of 13.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
If we take 640 away from 653, we end up with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 80

Advancing to step 5:
80 goes into 132 1 times with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 981.0
Subtract 80 from 132 to get 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 80

Step 6:
The number 80 fits into 525 6 times, leaving a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 9816.0
The remainder is 45 after subtracting 480 from 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 7:
When dividing 450 by 80, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9816.5
The remainder is 50 after subtracting 400 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 9816.56
Subtract 480 from 500 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.

Advancing to step 9:
The number 80 fits into 200 2 times, leaving a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 9816.562
Subtracting 160 from 200 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.

Going ahead to step 10:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 9816.5625
Deduct 400 from 400 and we're left 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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9816.5625
Deduct 0 from 0 and we're left 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.

Let's proceed to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9816.5625
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 quotient of the division is 9816.5625, and the remainder is 0.0.
