77865583 ÷ 555 
The aim is to understand the frequency of 555 in 77865583.

Moving on to step 1:
555 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 555

Let's proceed to step 2:
555 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 555

Let's proceed to step 3:
555 goes into 778 1 times with a remainder of 223.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 555 from 778, we get 223.
Include the next digit (6) from the dividend after 223, then repeat: 2236 / 555

Step 4:
555 goes into 2236 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 14.0
If we subtract 2220 from 2236, we get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 555

Let's proceed to step 5:
If we divide 165 by 555, we get 0 and a remainder of 165.
Write down 0 as next digit of the result. 
Result so far: 140.0
If we take 0 away from 165, we end up with 165.
Take the next digit (5) from the dividend and append it to 165, then repeat: 1655 / 555

On to step 6:
When dividing 1655 by 555, we get 2 with a remainder of 545.
The next digit of our result is 2. 
Result so far: 1402.0
If we subtract 1110 from 1655, we get 545.
Fetch the next digit (8) from the dividend, attach it to 545 and continue: 5458 / 555

Let's proceed to step 7:
555 goes into 5458 9 times with a remainder of 463.
Record the quotient 9 as the next digit in the result. 
Result so far: 14029.0
If we take 4995 away from 5458, we end up with 463.
Grab the next digit (3) from the dividend, add it to 463, then carry on: 4633 / 555

Advancing to step 8:
555 can be fit into 4633 8 times, resulting in a remainder of 193.
Put 8 as the next digit of the answer. 
Result so far: 140298.0
If we subtract 4440 from 4633, we get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Going ahead to step 9:
The number 555 fits into 1930 3 times, leaving a remainder of 265.
Put 3 as the next digit of the answer. 
Result so far: 140298.3
If we take 1665 away from 1930, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

On to step 10:
If we divide 2650 by 555, we get 4 and a remainder of 430.
Record the quotient 4 as the next digit in the result. 
Result so far: 140298.34
Subtract 2220 from 2650 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 11:
4300 divided by 555 is 7 with a remainder of 415.
Record the quotient 7 as the next digit in the result. 
Result so far: 140298.347
Subtracting 3885 from 4300 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

On to step 12:
555 can be fit into 4150 7 times, resulting in a remainder of 265.
Record the quotient 7 as the next digit in the result. 
Result so far: 140298.3477
If we subtract 3885 from 4150, we get 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

The final result is 140298.3477 with a remainder of 0.00265.
