We look at the division of 77499465 by 555 
The aim is to understand the frequency of 555 in 77499465.

Let's proceed to step 1:
When dividing 7 by 555, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 555

Step 2:
The number 555 fits into 77 0 times, leaving a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (4) from the dividend, attach it to 77 and continue: 774 / 555

Advancing to step 3:
555 can be fit into 774 1 times, resulting in a remainder of 219.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 555 from 774, we get 219.
Include the next digit (9) from the dividend after 219, then repeat: 2199 / 555

Step 4:
555 can be fit into 2199 3 times, resulting in a remainder of 534.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 534 after subtracting 1665 from 2199.
Fetch the next digit (9) from the dividend, attach it to 534 and continue: 5349 / 555

Going ahead to step 5:
5349 divided by 555 is 9 with a remainder of 354.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Deduct 4995 from 5349 and we're left with 354.
Fetch the next digit (4) from the dividend, attach it to 354 and continue: 3544 / 555

Moving on to step 6:
The number 555 fits into 3544 6 times, leaving a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 1396.0
The remainder is 214 after subtracting 3330 from 3544.
Include the next digit (6) from the dividend after 214, then repeat: 2146 / 555

Let's proceed to step 7:
If we divide 2146 by 555, we get 3 and a remainder of 481.
The number 3 becomes the next digit in our result. 
Result so far: 13963.0
Subtracting 1665 from 2146 leaves us with 481.
Grab the next digit (5) from the dividend, add it to 481, then carry on: 4815 / 555

Going ahead to step 8:
4815 divided by 555 is 8 with a remainder of 375.
Record the quotient 8 as the next digit in the result. 
Result so far: 139638.0
If we take 4440 away from 4815, we end up with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 9:
If we divide 3750 by 555, we get 6 and a remainder of 420.
Record the quotient 6 as the next digit in the result. 
Result so far: 139638.6
Subtracting 3330 from 3750 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Advancing to step 10:
If we divide 4200 by 555, we get 7 and a remainder of 315.
Record the quotient 7 as the next digit in the result. 
Result so far: 139638.67
If we take 3885 away from 4200, we end up with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 11:
555 goes into 3150 5 times with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 139638.675
Deduct 2775 from 3150 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Step 12:
555 goes into 3750 6 times with a remainder of 420.
Put 6 as the next digit of the answer. 
Result so far: 139638.6756
If we take 3330 away from 3750, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 13:
4200 divided by 555 is 7 with a remainder of 315.
Use 7 as the next digit of our solution. 
Result so far: 139638.67567
If we subtract 3885 from 4200, we get 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 14:
3150 divided by 555 is 5 with a remainder of 375.
Use 5 as the next digit of our solution. 
Result so far: 139638.675675
Deduct 2775 from 3150 and we're left with 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 15:
When dividing 3750 by 555, we get 6 with a remainder of 420.
The next digit of our result is 6. 
Result so far: 139638.6756756
If we subtract 3330 from 3750, we get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Step 16:
555 can be fit into 4200 7 times, resulting in a remainder of 315.
Put 7 as the next digit of the answer. 
Result so far: 139638.67567567
The remainder is 315 after subtracting 3885 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

In conclusion, the division gives 139638.67567567 with a balance of 3.15e-07.
