453870 divided by 53 
The aim is to understand the frequency of 53 in 453870.

Moving on to step 1:
If we divide 4 by 53, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 53

Going ahead to step 2:
The number 53 fits into 45 0 times, leaving a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 45, we get 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 53

Let's proceed to step 3:
53 can be fit into 453 8 times, resulting in a remainder of 29.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 29 after subtracting 424 from 453.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 53

Advancing to step 4:
The number 53 fits into 298 5 times, leaving a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 265 from 298, we get 33.
Include the next digit (7) from the dividend after 33, then repeat: 337 / 53

Advancing to step 5:
337 divided by 53 is 6 with a remainder of 19.
Write down 6 as next digit of the result. 
Result so far: 856.0
The remainder is 19 after subtracting 318 from 337.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 53

Going ahead to step 6:
If we divide 190 by 53, we get 3 and a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 8563.0
If we subtract 159 from 190, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 7:
The number 53 fits into 310 5 times, leaving a remainder of 45.
The next digit of our result is 5. 
Result so far: 8563.5
If we subtract 265 from 310, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
53 goes into 450 8 times with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 8563.58
The remainder is 26 after subtracting 424 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
260 divided by 53 is 4 with a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 8563.584
Deduct 212 from 260 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
When dividing 480 by 53, we get 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 8563.5849
Subtracting 477 from 480 leaves us 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 11:
The number 53 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 8563.5849
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 12:
300 divided by 53 is 5 with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 8563.584905
The remainder is 35 after subtracting 265 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 13:
The number 53 fits into 350 6 times, leaving a remainder of 32.
The next digit of our result is 6. 
Result so far: 8563.5849056
Deduct 318 from 350 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
If we divide 320 by 53, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 8563.58490566
Deduct 318 from 320 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 8563.58490566 and a remainder of 2e-09.
