888222 divided by 51 
The aim is to understand the frequency of 51 in 888222.

Step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 51

Going ahead to step 2:
88 divided by 51 is 1 with a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 51 from 88 and we're left with 37.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 51

Moving on to step 3:
The number 51 fits into 378 7 times, leaving a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 357 away from 378, we end up with 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 51

Let's proceed to step 4:
The number 51 fits into 212 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 174.0
The remainder is 8 after subtracting 204 from 212.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 51

Advancing to step 5:
51 can be fit into 82 1 times, resulting in a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1741.0
If we take 51 away from 82, we end up with 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 51

Going ahead to step 6:
312 divided by 51 is 6 with a remainder of 6.
The next digit of our result is 6. 
Result so far: 17416.0
The remainder is 6 after subtracting 306 from 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 51, we get 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 17416.1
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
51 can be fit into 90 1 times, resulting in a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 17416.11
Deduct 51 from 90 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 17416.11 with a remainder of 0.039.
