We look at the division of 68183651 by 555 
The aim is to understand the frequency of 555 in 68183651.

Advancing to step 1:
6 divided by 555 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 555

Moving on to step 2:
The number 555 fits into 68 0 times, leaving a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 555

Going ahead to step 3:
555 goes into 681 1 times with a remainder of 126.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 555 from 681 to get 126.
Fetch the next digit (8) from the dividend, attach it to 126 and continue: 1268 / 555

Going ahead to step 4:
If we divide 1268 by 555, we get 2 and a remainder of 158.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 1110 from 1268, we get 158.
Include the next digit (3) from the dividend after 158, then repeat: 1583 / 555

Advancing to step 5:
When dividing 1583 by 555, we get 2 with a remainder of 473.
Record the quotient 2 as the next digit in the result. 
Result so far: 122.0
If we take 1110 away from 1583, we end up with 473.
Grab the next digit (6) from the dividend, add it to 473, then carry on: 4736 / 555

Advancing to step 6:
If we divide 4736 by 555, we get 8 and a remainder of 296.
Put 8 as the next digit of the answer. 
Result so far: 1228.0
If we take 4440 away from 4736, we end up with 296.
Take the next digit (5) from the dividend and append it to 296, then repeat: 2965 / 555

Step 7:
555 can be fit into 2965 5 times, resulting in a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 12285.0
Deduct 2775 from 2965 and we're left with 190.
Include the next digit (1) from the dividend after 190, then repeat: 1901 / 555

On to step 8:
555 goes into 1901 3 times with a remainder of 236.
The number 3 becomes the next digit in our result. 
Result so far: 122853.0
If we subtract 1665 from 1901, we get 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 9:
2360 divided by 555 is 4 with a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 122853.4
Deduct 2220 from 2360 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
1400 divided by 555 is 2 with a remainder of 290.
Use 2 as the next digit of our solution. 
Result so far: 122853.42
Subtract 1110 from 1400 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 11:
2900 divided by 555 is 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 122853.425
Subtract 2775 from 2900 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 12:
1250 divided by 555 is 2 with a remainder of 140.
Record the quotient 2 as the next digit in the result. 
Result so far: 122853.4252
Deduct 1110 from 1250 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
1400 divided by 555 is 2 with a remainder of 290.
The number 2 becomes the next digit in our result. 
Result so far: 122853.42522
The remainder is 290 after subtracting 1110 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final result is 122853.42522 with a remainder of 0.00029.
