Let's divide 818195 by 77
The aim is to understand the frequency of 77 in 818195.

Going ahead to step 1:
77 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 77

Moving on to step 2:
81 divided by 77 is 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 77 from 81 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 77

Step 3:
77 goes into 48 0 times with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 48 leaves us with 48.
Take the next digit (1) from the dividend and append it to 48, then repeat: 481 / 77

Advancing to step 4:
When dividing 481 by 77, we get 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
If we subtract 462 from 481, we get 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 77

Advancing to step 5:
77 goes into 199 2 times with a remainder of 45.
Put 2 as the next digit of the answer. 
Result so far: 1062.0
Deduct 154 from 199 and we're left with 45.
Fetch the next digit (5) from the dividend, attach it to 45 and continue: 455 / 77

Step 6:
455 divided by 77 is 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 10625.0
Deduct 385 from 455 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.

Advancing to step 7:
77 goes into 700 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 10625.9
Subtract 693 from 700 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
If we divide 70 by 77, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10625.9
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
77 goes into 700 9 times with a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 10625.909
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 10:
70 divided by 77 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 10625.909
If we take 0 away from 70, we end up 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.

Step 11:
77 can be fit into 700 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 10625.90909
If we subtract 693 from 700, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
77 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10625.90909
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 13:
When dividing 700 by 77, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 10625.9090909
Subtract 693 from 700 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
77 can be fit into 70 0 times, resulting in a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10625.9090909
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 10625.9090909 and a remainder of 7e-08.
