443937 divided by 53 
The aim is to understand the frequency of 53 in 443937.

Step 1:
When dividing 4 by 53, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 53

Step 2:
When dividing 44 by 53, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Grab the next digit (3) from the dividend, add it to 44, then carry on: 443 / 53

Advancing to step 3:
443 divided by 53 is 8 with a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 424 away from 443, we end up with 19.
Bring next digit (9) of the dividend behind the 19 and repeat the process: 199 / 53

Let's proceed to step 4:
If we divide 199 by 53, we get 3 and a remainder of 40.
The next digit of our result is 3. 
Result so far: 83.0
Deduct 159 from 199 and we're left with 40.
Include the next digit (3) from the dividend after 40, then repeat: 403 / 53

Step 5:
The number 53 fits into 403 7 times, leaving a remainder of 32.
Use 7 as the next digit of our solution. 
Result so far: 837.0
Subtracting 371 from 403 leaves us with 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 53

Let's proceed to step 6:
When dividing 327 by 53, we get 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 8376.0
The remainder is 9 after subtracting 318 from 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 53, we get 1 and a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 8376.1
The remainder is 37 after subtracting 53 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 8:
If we divide 370 by 53, we get 6 and a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 8376.16
Subtracting 318 from 370 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 9:
53 can be fit into 520 9 times, resulting in a remainder of 43.
The next digit of our result is 9. 
Result so far: 8376.169
Subtract 477 from 520 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 10:
430 divided by 53 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 8376.1698
If we take 424 away from 430, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 11:
53 can be fit into 60 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 8376.16981
The remainder is 7 after subtracting 53 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
The number 53 fits into 70 1 times, leaving a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 8376.169811
Subtract 53 from 70 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 8376.169811 with a remainder of 1.7e-06.
