Let's divide 443365 by 53
The aim is to understand the frequency of 53 in 443365.

Moving on to step 1:
4 divided by 53 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 53

Let's proceed to step 2:
53 can be fit into 44 0 times, resulting in a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Append the next digit (3) from the dividend to 44 and continue with: 443 / 53

On to step 3:
When dividing 443 by 53, we get 8 with a remainder of 19.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 424 from 443 and we're left with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 53

Advancing to step 4:
When dividing 193 by 53, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Deduct 159 from 193 and we're left with 34.
Fetch the next digit (6) from the dividend, attach it to 34 and continue: 346 / 53

On to step 5:
53 can be fit into 346 6 times, resulting in a remainder of 28.
Put 6 as the next digit of the answer. 
Result so far: 836.0
Deduct 318 from 346 and we're left with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 53

Let's proceed to step 6:
The number 53 fits into 285 5 times, leaving a remainder of 20.
The next digit of our result is 5. 
Result so far: 8365.0
If we subtract 265 from 285, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
200 divided by 53 is 3 with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 8365.3
Deduct 159 from 200 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 8:
53 can be fit into 410 7 times, resulting in a remainder of 39.
The next digit of our result is 7. 
Result so far: 8365.37
Deduct 371 from 410 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
The number 53 fits into 390 7 times, leaving a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 8365.377
If we take 371 away from 390, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 8365.377 with a remainder of 0.0019.
