Let's divide 371009 by 80
The aim is to understand the frequency of 80 in 371009.

Step 1:
80 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 80

Moving on to step 2:
If we divide 37 by 80, we get 0 and a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 37 and we're left with 37.
Grab the next digit (1) from the dividend, add it to 37, then carry on: 371 / 80

Step 3:
80 can be fit into 371 4 times, resulting in a remainder of 51.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 51 after subtracting 320 from 371.
Include the next digit (0) from the dividend after 51, then repeat: 510 / 80

Step 4:
If we divide 510 by 80, we get 6 and a remainder of 30.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we subtract 480 from 510, we get 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 80

On to step 5:
300 divided by 80 is 3 with a remainder of 60.
Use 3 as the next digit of our solution. 
Result so far: 463.0
If we take 240 away from 300, we end up with 60.
Append the next digit (9) from the dividend to 60 and continue with: 609 / 80

Advancing to step 6:
80 can be fit into 609 7 times, resulting in a remainder of 49.
The next digit of our result is 7. 
Result so far: 4637.0
Subtract 560 from 609 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 7:
80 can be fit into 490 6 times, resulting in a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 4637.6
If we subtract 480 from 490, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 4637.61
If we take 80 away from 100, we end up 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.

Going ahead to step 9:
200 divided by 80 is 2 with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 4637.612
Subtract 160 from 200 to 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:
The number 80 fits into 400 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 4637.6125
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:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4637.6125
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.

On 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: 4637.6125
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.

After the division, we end up with 4637.6125 and a remainder of 0.0.
