Let's divide 726646 by 53
The aim is to understand the frequency of 53 in 726646.

Advancing to step 1:
53 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 53

On to step 2:
The number 53 fits into 72 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 53 from 72 to get 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 53

Moving on to step 3:
When dividing 196 by 53, we get 3 with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 159 from 196 leaves us with 37.
Take the next digit (6) from the dividend and append it to 37, then repeat: 376 / 53

On to step 4:
If we divide 376 by 53, we get 7 and a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
If we take 371 away from 376, we end up with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 53

Moving on to step 5:
54 divided by 53 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1371.0
Subtract 53 from 54 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 53

Let's proceed to step 6:
53 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 13710.0
The remainder is 16 after subtracting 0 from 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
53 can be fit into 160 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 13710.3
The remainder is 1 after subtracting 159 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 8:
When dividing 10 by 53, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 13710.3
If we subtract 0 from 10, we get 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 9:
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: 13710.301
If we take 53 away from 100, we end up 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 10:
53 goes into 470 8 times with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 13710.3018
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.

On to step 11:
53 can be fit into 460 8 times, resulting in a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 13710.30188
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.

Our division results in 13710.30188 with a remaining 3.6e-05.
