We divide 166854 by 53
The aim is to understand the frequency of 53 in 166854.

Let's proceed to step 1:
The number 53 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 53

Advancing to step 2:
The number 53 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 53

Let's proceed to step 3:
When dividing 166 by 53, we get 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 159 from 166 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 53

Let's proceed to step 4:
The number 53 fits into 78 1 times, leaving a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
If we take 53 away from 78, we end up with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 53

On to step 5:
53 can be fit into 255 4 times, resulting in a remainder of 43.
Use 4 as the next digit of our solution. 
Result so far: 314.0
Deduct 212 from 255 and we're left with 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 53

Step 6:
434 divided by 53 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 3148.0
The remainder is 10 after subtracting 424 from 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 53, we get 1 and a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 3148.1
Subtracting 53 from 100 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 8:
The number 53 fits into 470 8 times, leaving a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 3148.18
Subtract 424 from 470 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 9:
The number 53 fits into 460 8 times, leaving a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 3148.188
Deduct 424 from 460 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 3148.188 with a remainder of 0.0036.
