368690 ÷ 80 
The aim is to understand the frequency of 80 in 368690.

Let's proceed to step 1:
80 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 80

Moving on to step 2:
The number 80 fits into 36 0 times, leaving a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 80

Advancing to step 3:
80 goes into 368 4 times with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 320 away from 368, we end up with 48.
Fetch the next digit (6) from the dividend, attach it to 48 and continue: 486 / 80

Moving on to step 4:
80 can be fit into 486 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 46.0
Subtracting 480 from 486 leaves us with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 80

Step 5:
When dividing 69 by 80, we get 0 with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 460.0
If we subtract 0 from 69, we get 69.
Grab the next digit (0) from the dividend, add it to 69, then carry on: 690 / 80

Moving on to step 6:
80 goes into 690 8 times with a remainder of 50.
The number 8 becomes the next digit in our result. 
Result so far: 4608.0
If we take 640 away from 690, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 7:
The number 80 fits into 500 6 times, leaving a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 4608.6
If we subtract 480 from 500, we 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.

Let's proceed to step 8:
80 goes into 200 2 times with a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 4608.62
If we take 160 away from 200, we end up 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.

Moving on to step 9:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4608.625
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.

On to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4608.625
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.

Moving on to step 11:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4608.625
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.

The final result is 4608.625 with a remainder of 0.0.
