Let's divide 594618 by 72
The aim is to understand the frequency of 72 in 594618.

Advancing to step 1:
72 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 72

Going ahead to step 2:
72 can be fit into 59 0 times, resulting in a remainder of 59.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 59, we get 59.
Append the next digit (4) from the dividend to 59 and continue with: 594 / 72

Step 3:
72 can be fit into 594 8 times, resulting in a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 576 from 594 to get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 72

On to step 4:
When dividing 186 by 72, we get 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Subtract 144 from 186 to get 42.
Bring next digit (1) of the dividend behind the 42 and repeat the process: 421 / 72

Going ahead to step 5:
72 can be fit into 421 5 times, resulting in a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 825.0
Subtract 360 from 421 to get 61.
Include the next digit (8) from the dividend after 61, then repeat: 618 / 72

Step 6:
If we divide 618 by 72, we get 8 and a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 8258.0
If we take 576 away from 618, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
72 goes into 420 5 times with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 8258.5
Subtract 360 from 420 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
The number 72 fits into 600 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 8258.58
Subtract 576 from 600 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
The number 72 fits into 240 3 times, leaving a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 8258.583
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
72 goes into 240 3 times with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 8258.5833
Deduct 216 from 240 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 8258.5833, with a leftover of 0.00024.
