We're dividing 293559 by 51 
The aim is to understand the frequency of 51 in 293559.

Moving on to step 1:
The number 51 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 51

Advancing to step 2:
29 divided by 51 is 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 29, we end up with 29.
Append the next digit (3) from the dividend to 29 and continue with: 293 / 51

Moving on to step 3:
51 goes into 293 5 times with a remainder of 38.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 255 from 293 leaves us with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 51

Going ahead to step 4:
385 divided by 51 is 7 with a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 57.0
Subtracting 357 from 385 leaves us with 28.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 51

On to step 5:
51 goes into 285 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 575.0
Subtract 255 from 285 to get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 51

Going ahead to step 6:
When dividing 309 by 51, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 5756.0
Subtract 306 from 309 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
51 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 5756.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
51 goes into 300 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 5756.05
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 9:
450 divided by 51 is 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 5756.058
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 10:
51 can be fit into 420 8 times, resulting in a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5756.0588
Deduct 408 from 420 and we're left 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.

After the division, we end up with 5756.0588 and a remainder of 0.00012.
