812595 ÷ 77 
The aim is to understand the frequency of 77 in 812595.

On to step 1:
8 divided by 77 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 77

Going ahead to step 2:
When dividing 81 by 77, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 77 from 81, we get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 77

Advancing to step 3:
The number 77 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 42 to get 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 77

Going ahead to step 4:
425 divided by 77 is 5 with a remainder of 40.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Subtract 385 from 425 to get 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 77

On to step 5:
When dividing 409 by 77, we get 5 with a remainder of 24.
The next digit of our result is 5. 
Result so far: 1055.0
If we subtract 385 from 409, we get 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 77

Going ahead to step 6:
77 can be fit into 245 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 10553.0
Subtracting 231 from 245 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
77 can be fit into 140 1 times, resulting in a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 10553.1
If we take 77 away from 140, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 8:
77 goes into 630 8 times with a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 10553.18
The remainder is 14 after subtracting 616 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
If we divide 140 by 77, we get 1 and a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 10553.181
The remainder is 63 after subtracting 77 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Moving on to step 10:
If we divide 630 by 77, we get 8 and a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 10553.1818
If we take 616 away from 630, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
The number 77 fits into 140 1 times, leaving a remainder of 63.
The number 1 becomes the next digit in our result. 
Result so far: 10553.18181
If we take 77 away from 140, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 12:
630 divided by 77 is 8 with a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 10553.181818
If we subtract 616 from 630, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
77 can be fit into 140 1 times, resulting in a remainder of 63.
Record the quotient 1 as the next digit in the result. 
Result so far: 10553.1818181
The remainder is 63 after subtracting 77 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 14:
630 divided by 77 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 10553.18181818
If we subtract 616 from 630, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 10553.18181818 with a balance of 1.4e-08.
