175559 divided by 51 
The aim is to understand the frequency of 51 in 175559.

Let's proceed to step 1:
When dividing 1 by 51, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 51

Let's proceed to step 2:
51 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 51

Advancing to step 3:
175 divided by 51 is 3 with a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 153 from 175 leaves us with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 51

Advancing to step 4:
The number 51 fits into 225 4 times, leaving a remainder of 21.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 204 from 225 leaves us with 21.
Append the next digit (5) from the dividend to 21 and continue with: 215 / 51

Going ahead to step 5:
51 goes into 215 4 times with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 344.0
Subtracting 204 from 215 leaves us with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 51

Going ahead to step 6:
119 divided by 51 is 2 with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 3442.0
If we subtract 102 from 119, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
51 goes into 170 3 times with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 3442.3
If we take 153 away from 170, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 8:
The number 51 fits into 170 3 times, leaving a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 3442.33
If we subtract 153 from 170, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final outcome is 3442.33, with a leftover of 0.017.
