Let's divide 186666 by 53
The aim is to understand the frequency of 53 in 186666.

On to step 1:
53 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 53

Step 2:
53 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 53

On to step 3:
186 divided by 53 is 3 with a remainder of 27.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 27 after subtracting 159 from 186.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 53

Moving on to step 4:
276 divided by 53 is 5 with a remainder of 11.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we subtract 265 from 276, we get 11.
Include the next digit (6) from the dividend after 11, then repeat: 116 / 53

Let's proceed to step 5:
53 can be fit into 116 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 352.0
Subtracting 106 from 116 leaves us with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 53

Let's proceed to step 6:
The number 53 fits into 106 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 3522.0
If we take 106 away from 106, we end up with 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:
53 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3522.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
When dividing 0 by 53, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 3522.0
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.

Our division results in 3522.0 with a remaining 0.0.
