771935 ÷ 80 
The aim is to understand the frequency of 80 in 771935.

Step 1:
80 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 80

Step 2:
If we divide 77 by 80, we get 0 and a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (1) from the dividend and append it to 77, then repeat: 771 / 80

Step 3:
80 goes into 771 9 times with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 720 from 771 and we're left with 51.
Fetch the next digit (9) from the dividend, attach it to 51 and continue: 519 / 80

Moving on to step 4:
If we divide 519 by 80, we get 6 and a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
The remainder is 39 after subtracting 480 from 519.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 80

Step 5:
When dividing 393 by 80, we get 4 with a remainder of 73.
Put 4 as the next digit of the answer. 
Result so far: 964.0
If we take 320 away from 393, we end up with 73.
Append the next digit (5) from the dividend to 73 and continue with: 735 / 80

On to step 6:
80 can be fit into 735 9 times, resulting in a remainder of 15.
The number 9 becomes the next digit in our result. 
Result so far: 9649.0
Deduct 720 from 735 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 80, we get 1 and a remainder of 70.
The next digit of our result is 1. 
Result so far: 9649.1
Deduct 80 from 150 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
When dividing 700 by 80, we get 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 9649.18
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 9649.187
If we take 560 away from 600, 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.

Going ahead to step 10:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 9649.1875
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.

Let's proceed to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9649.1875
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.

Advancing to step 12:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9649.1875
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 quotient of the division is 9649.1875, and the remainder is 0.0.
