Let's divide 513128 by 53
The aim is to understand the frequency of 53 in 513128.

Step 1:
When dividing 5 by 53, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 53

Let's proceed to step 2:
The number 53 fits into 51 0 times, leaving a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Append the next digit (3) from the dividend to 51 and continue with: 513 / 53

Let's proceed to step 3:
53 can be fit into 513 9 times, resulting in a remainder of 36.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 477 from 513 and we're left with 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 53

Advancing to step 4:
53 can be fit into 361 6 times, resulting in a remainder of 43.
Put 6 as the next digit of the answer. 
Result so far: 96.0
If we subtract 318 from 361, we get 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 53

Advancing to step 5:
53 goes into 432 8 times with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 968.0
Subtract 424 from 432 to get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 53

Advancing to step 6:
88 divided by 53 is 1 with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 9681.0
Subtract 53 from 88 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
When dividing 350 by 53, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 9681.6
The remainder is 32 after subtracting 318 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 8:
53 goes into 320 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 9681.66
Subtracting 318 from 320 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 9681.66 and a remainder of 0.002.
