Let's divide 555078 by 51
The aim is to understand the frequency of 51 in 555078.

Moving on to step 1:
51 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 51

Advancing to step 2:
The number 51 fits into 55 1 times, leaving a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 51 from 55 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 51

Moving on to step 3:
45 divided by 51 is 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 45, we end up with 45.
Append the next digit (0) from the dividend to 45 and continue with: 450 / 51

Going ahead to step 4:
51 goes into 450 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 108.0
The remainder is 42 after subtracting 408 from 450.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 51

Moving on to step 5:
51 goes into 427 8 times with a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 1088.0
Subtracting 408 from 427 leaves us with 19.
Grab the next digit (8) from the dividend, add it to 19, then carry on: 198 / 51

Let's proceed to step 6:
When dividing 198 by 51, we get 3 with a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 10883.0
Subtracting 153 from 198 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
If we divide 450 by 51, we get 8 and a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 10883.8
If we take 408 away from 450, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 8:
51 goes into 420 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 10883.88
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 10883.88, with a leftover of 0.012.
