363223 divided by 53 
The aim is to understand the frequency of 53 in 363223.

Let's proceed to step 1:
3 divided by 53 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 53

Moving on to step 2:
The number 53 fits into 36 0 times, leaving a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 53

Step 3:
The number 53 fits into 363 6 times, leaving a remainder of 45.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 318 from 363 leaves us with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 53

Step 4:
The number 53 fits into 452 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 424 from 452 leaves us with 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 53

Let's proceed to step 5:
282 divided by 53 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 685.0
Subtracting 265 from 282 leaves us with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 53

Step 6:
When dividing 173 by 53, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 6853.0
The remainder is 14 after subtracting 159 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
When dividing 140 by 53, we get 2 with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 6853.2
Subtracting 106 from 140 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
53 goes into 340 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 6853.26
Deduct 318 from 340 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
53 goes into 220 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 6853.264
Deduct 212 from 220 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 53 is 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 6853.2641
Subtracting 53 from 80 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 11:
53 goes into 270 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 6853.26415
Deduct 265 from 270 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
When dividing 50 by 53, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 6853.26415
Subtracting 0 from 50 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 13:
The number 53 fits into 500 9 times, leaving a remainder of 23.
The next digit of our result is 9. 
Result so far: 6853.2641509
If we take 477 away from 500, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 14:
230 divided by 53 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 6853.26415094
If we subtract 212 from 230, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 6853.26415094, with a leftover of 1.8e-08.
