442748 divided by 53 
The aim is to understand the frequency of 53 in 442748.

Let's proceed to step 1:
53 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 53

Step 2:
53 can be fit into 44 0 times, resulting in a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 44 leaves us with 44.
Include the next digit (2) from the dividend after 44, then repeat: 442 / 53

Let's proceed to step 3:
53 can be fit into 442 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 424 from 442 and we're left with 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 53

Moving on to step 4:
If we divide 187 by 53, we get 3 and a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 83.0
Deduct 159 from 187 and we're left with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 53

On to step 5:
53 can be fit into 284 5 times, resulting in a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 835.0
Deduct 265 from 284 and we're left with 19.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 53

Advancing to step 6:
53 can be fit into 198 3 times, resulting in a remainder of 39.
Put 3 as the next digit of the answer. 
Result so far: 8353.0
The remainder is 39 after subtracting 159 from 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 7:
53 goes into 390 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 8353.7
Subtract 371 from 390 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
When dividing 190 by 53, we get 3 with a remainder of 31.
Put 3 as the next digit of the answer. 
Result so far: 8353.73
If we take 159 away from 190, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 9:
The number 53 fits into 310 5 times, leaving a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 8353.735
Deduct 265 from 310 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
If we divide 450 by 53, we get 8 and a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 8353.7358
If we take 424 away from 450, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
The number 53 fits into 260 4 times, leaving a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 8353.73584
The remainder is 48 after subtracting 212 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
53 can be fit into 480 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 8353.735849
If we take 477 away from 480, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
30 divided by 53 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8353.735849
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
53 can be fit into 300 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 8353.73584905
Subtract 265 from 300 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 8353.73584905, with a leftover of 3.5e-08.
