Let's divide 535677 by 80
The aim is to understand the frequency of 80 in 535677.

Advancing to step 1:
The number 80 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 80

On to step 2:
If we divide 53 by 80, we get 0 and a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 53 and we're left with 53.
Fetch the next digit (5) from the dividend, attach it to 53 and continue: 535 / 80

Let's proceed to step 3:
535 divided by 80 is 6 with a remainder of 55.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 480 from 535 and we're left with 55.
Bring next digit (6) of the dividend behind the 55 and repeat the process: 556 / 80

Moving on to step 4:
556 divided by 80 is 6 with a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
The remainder is 76 after subtracting 480 from 556.
Fetch the next digit (7) from the dividend, attach it to 76 and continue: 767 / 80

Going ahead to step 5:
The number 80 fits into 767 9 times, leaving a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 669.0
Subtract 720 from 767 to get 47.
Bring next digit (7) of the dividend behind the 47 and repeat the process: 477 / 80

Let's proceed to step 6:
When dividing 477 by 80, we get 5 with a remainder of 77.
Put 5 as the next digit of the answer. 
Result so far: 6695.0
If we take 400 away from 477, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 7:
If we divide 770 by 80, we get 9 and a remainder of 50.
The number 9 becomes the next digit in our result. 
Result so far: 6695.9
Subtract 720 from 770 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
80 goes into 500 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 6695.96
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.

Advancing to step 9:
80 goes into 200 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 6695.962
Deduct 160 from 200 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.

Going ahead to step 10:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 6695.9625
The remainder is 0 after subtracting 400 from 400.
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:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6695.9625
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.

On to step 12:
If we divide 0 by 80, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6695.9625
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 6695.9625 and a remainder of 0.0.
