We look at the division of 19157879 by 555 
The aim is to understand the frequency of 555 in 19157879.

On to step 1:
The number 555 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 555

Moving on to step 2:
The number 555 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 555

Step 3:
191 divided by 555 is 0 with a remainder of 191.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 191 to get 191.
Fetch the next digit (5) from the dividend, attach it to 191 and continue: 1915 / 555

Advancing to step 4:
If we divide 1915 by 555, we get 3 and a remainder of 250.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1665 from 1915 leaves us with 250.
Append the next digit (7) from the dividend to 250 and continue with: 2507 / 555

On to step 5:
2507 divided by 555 is 4 with a remainder of 287.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 2220 from 2507 and we're left with 287.
Fetch the next digit (8) from the dividend, attach it to 287 and continue: 2878 / 555

Let's proceed to step 6:
If we divide 2878 by 555, we get 5 and a remainder of 103.
Put 5 as the next digit of the answer. 
Result so far: 345.0
If we take 2775 away from 2878, we end up with 103.
Include the next digit (7) from the dividend after 103, then repeat: 1037 / 555

Advancing to step 7:
555 goes into 1037 1 times with a remainder of 482.
Use 1 as the next digit of our solution. 
Result so far: 3451.0
Subtract 555 from 1037 to get 482.
Grab the next digit (9) from the dividend, add it to 482, then carry on: 4829 / 555

On to step 8:
If we divide 4829 by 555, we get 8 and a remainder of 389.
The next digit of our result is 8. 
Result so far: 34518.0
If we take 4440 away from 4829, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Step 9:
3890 divided by 555 is 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 34518.7
Deduct 3885 from 3890 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
50 divided by 555 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 34518.7
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
If we divide 500 by 555, we get 0 and a remainder of 500.
The next digit of our result is 0. 
Result so far: 34518.7
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 34518.7 with a remainder of 0.05.
