We look at the division of 497887 by 73 
The aim is to understand the frequency of 73 in 497887.

Let's proceed to step 1:
73 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 73

Step 2:
When dividing 49 by 73, we get 0 with a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Fetch the next digit (7) from the dividend, attach it to 49 and continue: 497 / 73

Let's proceed to step 3:
The number 73 fits into 497 6 times, leaving a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 438 from 497 leaves us with 59.
Bring next digit (8) of the dividend behind the 59 and repeat the process: 598 / 73

On to step 4:
If we divide 598 by 73, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
If we subtract 584 from 598, we get 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 73

Advancing to step 5:
When dividing 148 by 73, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 682.0
Subtracting 146 from 148 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 73

Going ahead to step 6:
73 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 6820.0
The remainder is 27 after subtracting 0 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Step 7:
73 can be fit into 270 3 times, resulting in a remainder of 51.
Use 3 as the next digit of our solution. 
Result so far: 6820.3
Deduct 219 from 270 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 8:
When dividing 510 by 73, we get 6 with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 6820.36
If we subtract 438 from 510, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
73 can be fit into 720 9 times, resulting in a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 6820.369
Deduct 657 from 720 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 10:
The number 73 fits into 630 8 times, leaving a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 6820.3698
The remainder is 46 after subtracting 584 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
If we divide 460 by 73, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 6820.36986
Subtracting 438 from 460 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 12:
When dividing 220 by 73, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 6820.369863
If we take 219 away from 220, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 13:
If we divide 10 by 73, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 6820.369863
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
When dividing 100 by 73, we get 1 with a remainder of 27.
Write down 1 as next digit of the result. 
Result so far: 6820.36986301
Subtract 73 from 100 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 6820.36986301 with a remainder of 2.7e-08.
