820483 divided by 77 
The aim is to understand the frequency of 77 in 820483.

On to step 1:
When dividing 8 by 77, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 77

On to step 2:
82 divided by 77 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 77 away from 82, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 77

Let's proceed to step 3:
77 can be fit into 50 0 times, resulting in a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 50 after subtracting 0 from 50.
Append the next digit (4) from the dividend to 50 and continue with: 504 / 77

Step 4:
If we divide 504 by 77, we get 6 and a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
Subtracting 462 from 504 leaves us with 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 77

Let's proceed to step 5:
428 divided by 77 is 5 with a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 1065.0
Subtracting 385 from 428 leaves us with 43.
Fetch the next digit (3) from the dividend, attach it to 43 and continue: 433 / 77

Going ahead to step 6:
433 divided by 77 is 5 with a remainder of 48.
The next digit of our result is 5. 
Result so far: 10655.0
If we take 385 away from 433, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
When dividing 480 by 77, we get 6 with a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 10655.6
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
When dividing 180 by 77, we get 2 with a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 10655.62
Deduct 154 from 180 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
If we divide 260 by 77, we get 3 and a remainder of 29.
Put 3 as the next digit of the answer. 
Result so far: 10655.623
The remainder is 29 after subtracting 231 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 10:
When dividing 290 by 77, we get 3 with a remainder of 59.
Record the quotient 3 as the next digit in the result. 
Result so far: 10655.6233
Deduct 231 from 290 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 10655.6233, with a leftover of 0.00059.
