301051 divided by 80 
The aim is to understand the frequency of 80 in 301051.

On to step 1:
If we divide 3 by 80, we get 0 and a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 80

Going ahead to step 2:
The number 80 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Include the next digit (1) from the dividend after 30, then repeat: 301 / 80

On to step 3:
80 can be fit into 301 3 times, resulting in a remainder of 61.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 240 from 301, we get 61.
Append the next digit (0) from the dividend to 61 and continue with: 610 / 80

Moving on to step 4:
80 goes into 610 7 times with a remainder of 50.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Deduct 560 from 610 and we're left with 50.
Grab the next digit (5) from the dividend, add it to 50, then carry on: 505 / 80

Let's proceed to step 5:
505 divided by 80 is 6 with a remainder of 25.
Use 6 as the next digit of our solution. 
Result so far: 376.0
If we subtract 480 from 505, we get 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 80

Going ahead to step 6:
80 can be fit into 251 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3763.0
Subtracting 240 from 251 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
80 goes into 110 1 times with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 3763.1
Subtract 80 from 110 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.

Step 8:
80 can be fit into 300 3 times, resulting in a remainder of 60.
Put 3 as the next digit of the answer. 
Result so far: 3763.13
Subtracting 240 from 300 leaves us 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:
The number 80 fits into 600 7 times, leaving a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 3763.137
If we subtract 560 from 600, 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.

On to step 10:
400 divided by 80 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3763.1375
If we take 400 away from 400, 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.

Moving on to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 3763.1375
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.

Step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 3763.1375
Subtract 0 from 0 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.

After the division, we end up with 3763.1375 and a remainder of 0.0.
