Let's divide 77189054 by 555
The aim is to understand the frequency of 555 in 77189054.

Let's proceed to step 1:
555 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 555

Step 2:
555 can be fit into 77 0 times, resulting in 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.
Include the next digit (1) from the dividend after 77, then repeat: 771 / 555

Let's proceed to step 3:
The number 555 fits into 771 1 times, leaving a remainder of 216.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 555 from 771 to get 216.
Bring next digit (8) of the dividend behind the 216 and repeat the process: 2168 / 555

Moving on to step 4:
If we divide 2168 by 555, we get 3 and a remainder of 503.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtract 1665 from 2168 to get 503.
Fetch the next digit (9) from the dividend, attach it to 503 and continue: 5039 / 555

On to step 5:
555 can be fit into 5039 9 times, resulting in a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 139.0
Subtract 4995 from 5039 to get 44.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 555

Step 6:
The number 555 fits into 440 0 times, leaving a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 1390.0
Subtract 0 from 440 to get 440.
Take the next digit (5) from the dividend and append it to 440, then repeat: 4405 / 555

On to step 7:
555 goes into 4405 7 times with a remainder of 520.
The number 7 becomes the next digit in our result. 
Result so far: 13907.0
Subtracting 3885 from 4405 leaves us with 520.
Grab the next digit (4) from the dividend, add it to 520, then carry on: 5204 / 555

Going ahead to step 8:
5204 divided by 555 is 9 with a remainder of 209.
The number 9 becomes the next digit in our result. 
Result so far: 139079.0
Deduct 4995 from 5204 and we're left with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Let's proceed to step 9:
When dividing 2090 by 555, we get 3 with a remainder of 425.
Put 3 as the next digit of the answer. 
Result so far: 139079.3
Subtract 1665 from 2090 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 10:
555 can be fit into 4250 7 times, resulting in a remainder of 365.
The next digit of our result is 7. 
Result so far: 139079.37
Deduct 3885 from 4250 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 11:
3650 divided by 555 is 6 with a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 139079.376
Deduct 3330 from 3650 and we're left with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Advancing to step 12:
When dividing 3200 by 555, we get 5 with a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 139079.3765
Subtract 2775 from 3200 to get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Moving on to step 13:
555 goes into 4250 7 times with a remainder of 365.
Use 7 as the next digit of our solution. 
Result so far: 139079.37657
Subtracting 3885 from 4250 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 14:
555 can be fit into 3650 6 times, resulting in a remainder of 320.
Write down 6 as next digit of the result. 
Result so far: 139079.376576
The remainder is 320 after subtracting 3330 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 15:
555 goes into 3200 5 times with a remainder of 425.
The next digit of our result is 5. 
Result so far: 139079.3765765
If we subtract 2775 from 3200, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 16:
555 goes into 4250 7 times with a remainder of 365.
Record the quotient 7 as the next digit in the result. 
Result so far: 139079.37657657
If we take 3885 away from 4250, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

The final result is 139079.37657657 with a remainder of 3.65e-07.
