Let's divide 489573 by 73
The aim is to understand the frequency of 73 in 489573.

Advancing to step 1:
73 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 73

Step 2:
48 divided by 73 is 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 48 after subtracting 0 from 48.
Include the next digit (9) from the dividend after 48, then repeat: 489 / 73

Moving on to step 3:
If we divide 489 by 73, we get 6 and a remainder of 51.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 438 away from 489, we end up with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 73

On to step 4:
The number 73 fits into 515 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtract 511 from 515 to get 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 73

Advancing to step 5:
If we divide 47 by 73, we get 0 and a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 670.0
If we take 0 away from 47, we end up with 47.
Fetch the next digit (3) from the dividend, attach it to 47 and continue: 473 / 73

Going ahead to step 6:
73 goes into 473 6 times with a remainder of 35.
The next digit of our result is 6. 
Result so far: 6706.0
Deduct 438 from 473 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
350 divided by 73 is 4 with a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 6706.4
If we subtract 292 from 350, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
When dividing 580 by 73, we get 7 with a remainder of 69.
Put 7 as the next digit of the answer. 
Result so far: 6706.47
If we take 511 away from 580, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
73 goes into 690 9 times with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 6706.479
If we take 657 away from 690, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
The number 73 fits into 330 4 times, leaving a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 6706.4794
Subtract 292 from 330 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 11:
The number 73 fits into 380 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 6706.47945
If we take 365 away from 380, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
73 can be fit into 150 2 times, resulting in a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 6706.479452
The remainder is 4 after subtracting 146 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
If we divide 40 by 73, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 6706.479452
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
73 goes into 400 5 times with a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 6706.47945205
If we take 365 away from 400, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 6706.47945205, with a leftover of 3.5e-08.
