We're dividing 213918 by 53 
The aim is to understand the frequency of 53 in 213918.

Moving on to step 1:
53 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 53

Let's proceed to step 2:
21 divided by 53 is 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 53

On to step 3:
If we divide 213 by 53, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 1 after subtracting 212 from 213.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 53

Advancing to step 4:
53 can be fit into 19 0 times, resulting in a remainder of 19.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 19 to get 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 53

On to step 5:
The number 53 fits into 191 3 times, leaving a remainder of 32.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
Deduct 159 from 191 and we're left with 32.
Fetch the next digit (8) from the dividend, attach it to 32 and continue: 328 / 53

Going ahead to step 6:
328 divided by 53 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 4036.0
Subtracting 318 from 328 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 53 is 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 4036.1
If we subtract 53 from 100, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 8:
53 can be fit into 470 8 times, resulting in a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 4036.18
Deduct 424 from 470 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 9:
If we divide 460 by 53, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 4036.188
The remainder is 36 after subtracting 424 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Our division results in 4036.188 with a remaining 0.0036.
