604713 ÷ 73 
The aim is to understand the frequency of 73 in 604713.

Step 1:
6 divided by 73 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 73

On to step 2:
73 goes into 60 0 times with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 60 and we're left with 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 73

Going ahead to step 3:
73 can be fit into 604 8 times, resulting in a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 584 away from 604, we end up with 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 73

Let's proceed to step 4:
207 divided by 73 is 2 with a remainder of 61.
Use 2 as the next digit of our solution. 
Result so far: 82.0
The remainder is 61 after subtracting 146 from 207.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 73

On to step 5:
The number 73 fits into 611 8 times, leaving a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 828.0
Subtract 584 from 611 to get 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 73

Let's proceed to step 6:
73 can be fit into 273 3 times, resulting in a remainder of 54.
Write down 3 as next digit of the result. 
Result so far: 8283.0
Subtract 219 from 273 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 7:
When dividing 540 by 73, we get 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 8283.7
Subtracting 511 from 540 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 8:
When dividing 290 by 73, we get 3 with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 8283.73
If we take 219 away from 290, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 9:
710 divided by 73 is 9 with a remainder of 53.
The next digit of our result is 9. 
Result so far: 8283.739
Subtract 657 from 710 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 10:
73 can be fit into 530 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 8283.7397
If we take 511 away from 530, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 11:
73 goes into 190 2 times with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 8283.73972
If we subtract 146 from 190, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 12:
The number 73 fits into 440 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 8283.739726
The remainder is 2 after subtracting 438 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
73 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8283.739726
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
When dividing 200 by 73, we get 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 8283.73972602
Subtract 146 from 200 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

After the division, we end up with 8283.73972602 and a remainder of 5.4e-08.
