We look at the division of 490574 by 73 
The aim is to understand the frequency of 73 in 490574.

Moving on to step 1:
When dividing 4 by 73, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 73

Going ahead to step 2:
73 goes into 49 0 times with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 73

Moving on to step 3:
73 goes into 490 6 times with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 438 from 490 and we're left with 52.
Grab the next digit (5) from the dividend, add it to 52, then carry on: 525 / 73

Step 4:
525 divided by 73 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 67.0
Subtract 511 from 525 to get 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 73

Let's proceed to step 5:
73 goes into 147 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 672.0
If we take 146 away from 147, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 73

Step 6:
The number 73 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 6720.0
Subtracting 0 from 14 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
73 goes into 140 1 times with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 6720.1
The remainder is 67 after subtracting 73 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 8:
670 divided by 73 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 6720.19
The remainder is 13 after subtracting 657 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
When dividing 130 by 73, we get 1 with a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 6720.191
Subtract 73 from 130 to 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.

Moving on to step 10:
73 goes into 570 7 times with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 6720.1917
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.

On to step 11:
73 can be fit into 590 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 6720.19178
Subtracting 584 from 590 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
The number 73 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 6720.19178
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 13:
If we divide 600 by 73, we get 8 and a remainder of 16.
The next digit of our result is 8. 
Result so far: 6720.1917808
Subtracting 584 from 600 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
If we divide 160 by 73, we get 2 and a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 6720.19178082
Subtracting 146 from 160 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 6720.19178082 with a remainder of 1.4e-08.
