789090 divided by 53 
The aim is to understand the frequency of 53 in 789090.

Going ahead to step 1:
7 divided by 53 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 53

Advancing to step 2:
53 goes into 78 1 times with a remainder of 25.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 25 after subtracting 53 from 78.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 53

Let's proceed to step 3:
When dividing 259 by 53, we get 4 with a remainder of 47.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we take 212 away from 259, we end up with 47.
Fetch the next digit (0) from the dividend, attach it to 47 and continue: 470 / 53

Moving on to step 4:
470 divided by 53 is 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 148.0
Subtracting 424 from 470 leaves us with 46.
Append the next digit (9) from the dividend to 46 and continue with: 469 / 53

On to step 5:
53 goes into 469 8 times with a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 1488.0
If we take 424 away from 469, we end up with 45.
Take the next digit (0) from the dividend and append it to 45, then repeat: 450 / 53

Advancing to step 6:
53 goes into 450 8 times with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 14888.0
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.

Advancing to step 7:
260 divided by 53 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 14888.4
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.

Advancing to step 8:
480 divided by 53 is 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 14888.49
Subtract 477 from 480 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
53 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 14888.49
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
53 can be fit into 300 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 14888.4905
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.

Let's proceed to step 11:
53 can be fit into 350 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 14888.49056
If we take 318 away from 350, we end up 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 12:
53 goes into 320 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 14888.490566
If we subtract 318 from 320, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 14888.490566 with a balance of 2e-07.
