723104 divided by 77 
The aim is to understand the frequency of 77 in 723104.

Step 1:
If we divide 7 by 77, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 77

Going ahead to step 2:
When dividing 72 by 77, we get 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 77

Moving on to step 3:
77 can be fit into 723 9 times, resulting in a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 693 away from 723, we end up with 30.
Take the next digit (1) from the dividend and append it to 30, then repeat: 301 / 77

On to step 4:
The number 77 fits into 301 3 times, leaving a remainder of 70.
Use 3 as the next digit of our solution. 
Result so far: 93.0
Subtracting 231 from 301 leaves us with 70.
Grab the next digit (0) from the dividend, add it to 70, then carry on: 700 / 77

Advancing to step 5:
700 divided by 77 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 939.0
If we subtract 693 from 700, we get 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 77

Advancing to step 6:
The number 77 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 9390.0
The remainder is 74 after subtracting 0 from 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
The number 77 fits into 740 9 times, leaving a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 9390.9
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 8:
When dividing 470 by 77, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 9390.96
Subtract 462 from 470 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
80 divided by 77 is 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 9390.961
Subtracting 77 from 80 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
The number 77 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 9390.961
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
77 can be fit into 300 3 times, resulting in a remainder of 69.
Record the quotient 3 as the next digit in the result. 
Result so far: 9390.96103
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 12:
The number 77 fits into 690 8 times, leaving a remainder of 74.
The next digit of our result is 8. 
Result so far: 9390.961038
Subtract 616 from 690 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 13:
740 divided by 77 is 9 with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 9390.9610389
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 14:
77 can be fit into 470 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 9390.96103896
Deduct 462 from 470 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 9390.96103896 and a remainder of 8e-09.
