Let's divide 257680 by 53
The aim is to understand the frequency of 53 in 257680.

Step 1:
2 divided by 53 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 53

On to step 2:
When dividing 25 by 53, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 53

Step 3:
53 goes into 257 4 times with a remainder of 45.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 45 after subtracting 212 from 257.
Fetch the next digit (6) from the dividend, attach it to 45 and continue: 456 / 53

On to step 4:
When dividing 456 by 53, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 32 after subtracting 424 from 456.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 53

Let's proceed to step 5:
53 goes into 328 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 486.0
The remainder is 10 after subtracting 318 from 328.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 53

Moving on to step 6:
100 divided by 53 is 1 with a remainder of 47.
The next digit of our result is 1. 
Result so far: 4861.0
Subtract 53 from 100 to 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.

On to step 7:
53 can be fit into 470 8 times, resulting in a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 4861.8
If we subtract 424 from 470, we 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.

Let's proceed to step 8:
When dividing 460 by 53, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 4861.88
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 quotient of the division is 4861.88, and the remainder is 0.036.
