We look at the division of 568222 by 73 
The aim is to understand the frequency of 73 in 568222.

On to step 1:
The number 73 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 73

Moving on to step 2:
When dividing 56 by 73, we get 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 73

Going ahead to step 3:
The number 73 fits into 568 7 times, leaving a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 57 after subtracting 511 from 568.
Append the next digit (2) from the dividend to 57 and continue with: 572 / 73

Moving on to step 4:
73 goes into 572 7 times with a remainder of 61.
Write down 7 as next digit of the result. 
Result so far: 77.0
Deduct 511 from 572 and we're left with 61.
Grab the next digit (2) from the dividend, add it to 61, then carry on: 612 / 73

Moving on to step 5:
73 can be fit into 612 8 times, resulting in a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 778.0
If we subtract 584 from 612, we get 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 73

Step 6:
If we divide 282 by 73, we get 3 and a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 7783.0
If we subtract 219 from 282, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 7:
630 divided by 73 is 8 with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 7783.8
If we subtract 584 from 630, we get 46.
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 8:
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: 7783.86
Deduct 438 from 460 and we're left 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.

Advancing to step 9:
220 divided by 73 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 7783.863
Subtract 219 from 220 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
If we divide 10 by 73, we get 0 and a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 7783.863
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.

Moving on to step 11:
If we divide 100 by 73, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 7783.86301
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.

Moving on to step 12:
If we divide 270 by 73, we get 3 and a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 7783.863013
The remainder is 51 after subtracting 219 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 13:
When dividing 510 by 73, we get 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 7783.8630136
Subtract 438 from 510 to 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.

Let's proceed to step 14:
When dividing 720 by 73, we get 9 with a remainder of 63.
The next digit of our result is 9. 
Result so far: 7783.86301369
Subtracting 657 from 720 leaves us 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.

After the division, we end up with 7783.86301369 and a remainder of 6.3e-08.
