942801 ÷ 80 
The aim is to understand the frequency of 80 in 942801.

On to step 1:
80 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 80

Going ahead to step 2:
The number 80 fits into 94 1 times, leaving a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 80 from 94 to get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 80

Let's proceed to step 3:
80 goes into 142 1 times with a remainder of 62.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 80 from 142 leaves us with 62.
Fetch the next digit (8) from the dividend, attach it to 62 and continue: 628 / 80

Let's proceed to step 4:
80 goes into 628 7 times with a remainder of 68.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtracting 560 from 628 leaves us with 68.
Append the next digit (0) from the dividend to 68 and continue with: 680 / 80

Let's proceed to step 5:
680 divided by 80 is 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 1178.0
Deduct 640 from 680 and we're left with 40.
Grab the next digit (1) from the dividend, add it to 40, then carry on: 401 / 80

On to step 6:
The number 80 fits into 401 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 11785.0
Subtract 400 from 401 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
If we divide 10 by 80, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 11785.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 80 fits into 100 1 times, leaving a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 11785.01
Subtracting 80 from 100 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
The next digit of our result is 2. 
Result so far: 11785.012
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.

Advancing to step 10:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 11785.0125
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.

Going ahead 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: 11785.0125
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.

Going ahead to step 12:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11785.0125
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.

After the division, we end up with 11785.0125 and a remainder of 0.0.
