807005 divided by 77 
The aim is to understand the frequency of 77 in 807005.

Step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 77

Step 2:
80 divided by 77 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 77 from 80 to get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 77

Step 3:
If we divide 37 by 77, we get 0 and a remainder of 37.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 37 after subtracting 0 from 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 77

Going ahead to step 4:
77 can be fit into 370 4 times, resulting in a remainder of 62.
Write down 4 as next digit of the result. 
Result so far: 104.0
If we take 308 away from 370, we end up with 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 77

Let's proceed to step 5:
When dividing 620 by 77, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1048.0
The remainder is 4 after subtracting 616 from 620.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 77

Step 6:
77 can be fit into 45 0 times, resulting in a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 10480.0
If we take 0 away from 45, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
77 can be fit into 450 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 10480.5
The remainder is 65 after subtracting 385 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 8:
The number 77 fits into 650 8 times, leaving a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 10480.58
Deduct 616 from 650 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
77 can be fit into 340 4 times, resulting in a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 10480.584
Subtract 308 from 340 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 10:
The number 77 fits into 320 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 10480.5844
If we subtract 308 from 320, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 10480.5844, with a leftover of 0.00012.
