We look at the division of 585723 by 73 
The aim is to understand the frequency of 73 in 585723.

Going ahead to step 1:
If we divide 5 by 73, we get 0 and 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.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 73

Advancing to step 2:
When dividing 58 by 73, we get 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Take the next digit (5) from the dividend and append it to 58, then repeat: 585 / 73

On to step 3:
The number 73 fits into 585 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 1 after subtracting 584 from 585.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 73

On to step 4:
73 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
The remainder is 17 after subtracting 0 from 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 73

Moving on to step 5:
73 goes into 172 2 times with a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 802.0
The remainder is 26 after subtracting 146 from 172.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 73

Moving on to step 6:
If we divide 263 by 73, we get 3 and a remainder of 44.
Record the quotient 3 as the next digit in the result. 
Result so far: 8023.0
If we take 219 away from 263, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 7:
73 goes into 440 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 8023.6
Deduct 438 from 440 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.

Let's proceed to step 8:
73 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8023.6
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
If we divide 200 by 73, we get 2 and a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 8023.602
The remainder is 54 after subtracting 146 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 10:
The number 73 fits into 540 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 8023.6027
Subtracting 511 from 540 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 11:
290 divided by 73 is 3 with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 8023.60273
If we subtract 219 from 290, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
The number 73 fits into 710 9 times, leaving a remainder of 53.
Write down 9 as next digit of the result. 
Result so far: 8023.602739
If we subtract 657 from 710, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 13:
The number 73 fits into 530 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 8023.6027397
If we subtract 511 from 530, we 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.

Step 14:
73 goes into 190 2 times with a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 8023.60273972
The remainder is 44 after subtracting 146 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 8023.60273972 with a balance of 4.4e-08.
