341604 ÷ 80 
The aim is to understand the frequency of 80 in 341604.

Step 1:
3 divided by 80 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 80

Step 2:
When dividing 34 by 80, we get 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 80

On to step 3:
80 can be fit into 341 4 times, resulting in a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 320 from 341 to get 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 80

On to step 4:
80 can be fit into 216 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 42.0
If we take 160 away from 216, we end up with 56.
Take the next digit (0) from the dividend and append it to 56, then repeat: 560 / 80

Moving on to step 5:
80 goes into 560 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 427.0
Deduct 560 from 560 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 80

Going ahead to step 6:
If we divide 4 by 80, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 4270.0
If we subtract 0 from 4, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 80, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 4270.0
The remainder is 40 after subtracting 0 from 40.
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 8:
If we divide 400 by 80, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 4270.05
Subtracting 400 from 400 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.

Advancing to step 9:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4270.05
If we subtract 0 from 0, we 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 10:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4270.05
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 final outcome is 4270.05, with a leftover of 0.0.
