We look at the division of 582889 by 73 
The aim is to understand the frequency of 73 in 582889.

Advancing to step 1:
The number 73 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 73

Going ahead to step 2:
73 can be fit into 58 0 times, resulting in a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Bring next digit (2) of the dividend behind the 58 and repeat the process: 582 / 73

On to step 3:
73 goes into 582 7 times with a remainder of 71.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 511 from 582 and we're left with 71.
Bring next digit (8) of the dividend behind the 71 and repeat the process: 718 / 73

Let's proceed to step 4:
The number 73 fits into 718 9 times, leaving a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
If we take 657 away from 718, we end up with 61.
Take the next digit (8) from the dividend and append it to 61, then repeat: 618 / 73

Moving on to step 5:
The number 73 fits into 618 8 times, leaving a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 798.0
If we subtract 584 from 618, we get 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 73

Let's proceed to step 6:
349 divided by 73 is 4 with a remainder of 57.
Use 4 as the next digit of our solution. 
Result so far: 7984.0
Deduct 292 from 349 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Advancing to step 7:
73 goes into 570 7 times with a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 7984.7
Deduct 511 from 570 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 8:
When dividing 590 by 73, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 7984.78
The remainder is 6 after subtracting 584 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
73 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 7984.78
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 10:
If we divide 600 by 73, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7984.7808
The remainder is 16 after subtracting 584 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 11:
The number 73 fits into 160 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 7984.78082
Subtract 146 from 160 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
When dividing 140 by 73, we get 1 with a remainder of 67.
Record the quotient 1 as the next digit in the result. 
Result so far: 7984.780821
If we take 73 away from 140, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 13:
670 divided by 73 is 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 7984.7808219
Subtract 657 from 670 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 14:
The number 73 fits into 130 1 times, leaving a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 7984.78082191
If we subtract 73 from 130, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

The final outcome is 7984.78082191, with a leftover of 5.7e-08.
