42330 divided by 51 
The aim is to understand the frequency of 51 in 42330.

Moving on to step 1:
4 divided by 51 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 51

Step 2:
The number 51 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 51

Going ahead to step 3:
If we divide 423 by 51, we get 8 and a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 15 after subtracting 408 from 423.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 51

On to step 4:
51 can be fit into 153 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 83.0
Deduct 153 from 153 and we're left with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 51

Let's proceed to step 5:
When dividing 0 by 51, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 830.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 6:
51 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 830.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
If we divide 0 by 51, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 830.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 830.0 with a remainder of 0.0.
