We're dividing 844452 by 51 
The aim is to understand the frequency of 51 in 844452.

Going ahead to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 51

On to step 2:
84 divided by 51 is 1 with a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 84, we end up with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 51

Let's proceed to step 3:
334 divided by 51 is 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtracting 306 from 334 leaves us with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 51

Going ahead to step 4:
The number 51 fits into 284 5 times, leaving a remainder of 29.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
Deduct 255 from 284 and we're left with 29.
Bring next digit (5) of the dividend behind the 29 and repeat the process: 295 / 51

Moving on to step 5:
295 divided by 51 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 1655.0
If we take 255 away from 295, we end up with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 51

Going ahead to step 6:
402 divided by 51 is 7 with a remainder of 45.
The next digit of our result is 7. 
Result so far: 16557.0
Deduct 357 from 402 and we're left 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.

Advancing to step 7:
450 divided by 51 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 16557.8
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
51 goes into 420 8 times with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 16557.88
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 16557.88, with a leftover of 0.012.
