Let's divide 945640 by 80
The aim is to understand the frequency of 80 in 945640.

Step 1:
80 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 80

Moving on to step 2:
When dividing 94 by 80, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 80 from 94 to get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 80

Going ahead to step 3:
The number 80 fits into 145 1 times, leaving a remainder of 65.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 80 from 145, we get 65.
Grab the next digit (6) from the dividend, add it to 65, then carry on: 656 / 80

Advancing to step 4:
When dividing 656 by 80, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Subtracting 640 from 656 leaves us with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 80

Going ahead to step 5:
The number 80 fits into 164 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 1182.0
If we subtract 160 from 164, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 80

Let's proceed to step 6:
The number 80 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 11820.0
Deduct 0 from 40 and we're left 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.

Advancing to step 7:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11820.5
If we subtract 400 from 400, 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.

Moving on to step 8:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11820.5
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.

Advancing to step 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11820.5
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.

After the division, we end up with 11820.5 and a remainder of 0.0.
