583923 ÷ 53 
The aim is to understand the frequency of 53 in 583923.

Let's proceed to step 1:
53 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 53

Going ahead to step 2:
The number 53 fits into 58 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 53 from 58 to get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 53

Moving on to step 3:
53 can be fit into 53 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 53 from 53 and we're left with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 53

Moving on to step 4:
When dividing 9 by 53, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 110.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 53

Let's proceed to step 5:
92 divided by 53 is 1 with a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 1101.0
If we subtract 53 from 92, we get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 53

Going ahead to step 6:
53 can be fit into 393 7 times, resulting in a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 11017.0
Subtract 371 from 393 to get 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 7:
53 goes into 220 4 times with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 11017.4
If we subtract 212 from 220, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
80 divided by 53 is 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 11017.41
If we take 53 away from 80, we end up 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 9:
53 goes into 270 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11017.415
Subtract 265 from 270 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
When dividing 50 by 53, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 11017.415
Subtract 0 from 50 to get 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 11:
If we divide 500 by 53, we get 9 and a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 11017.41509
Subtracting 477 from 500 leaves us 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.

Moving on to step 12:
53 can be fit into 230 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 11017.415094
Subtract 212 from 230 to 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.

On to step 13:
When dividing 180 by 53, we get 3 with a remainder of 21.
The number 3 becomes the next digit in our result. 
Result so far: 11017.4150943
If we subtract 159 from 180, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 14:
If we divide 210 by 53, we get 3 and a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 11017.41509433
If we subtract 159 from 210, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 11017.41509433 and a remainder of 5.1e-08.
