508423 ÷ 73 
The aim is to understand the frequency of 73 in 508423.

Let's proceed to step 1:
73 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 73

On to step 2:
When dividing 50 by 73, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 50 to get 50.
Bring next digit (8) of the dividend behind the 50 and repeat the process: 508 / 73

Going ahead to step 3:
When dividing 508 by 73, we get 6 with a remainder of 70.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 438 from 508, we get 70.
Append the next digit (4) from the dividend to 70 and continue with: 704 / 73

Let's proceed to step 4:
73 goes into 704 9 times with a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Subtract 657 from 704 to get 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 73

Moving on to step 5:
472 divided by 73 is 6 with a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 696.0
Deduct 438 from 472 and we're left with 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 73

Moving on to step 6:
343 divided by 73 is 4 with a remainder of 51.
The next digit of our result is 4. 
Result so far: 6964.0
Deduct 292 from 343 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.

Moving on to step 7:
When dividing 510 by 73, we get 6 with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 6964.6
Subtracting 438 from 510 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 8:
720 divided by 73 is 9 with a remainder of 63.
Use 9 as the next digit of our solution. 
Result so far: 6964.69
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.

Moving on to step 9:
73 can be fit into 630 8 times, resulting in a remainder of 46.
The number 8 becomes the next digit in our result. 
Result so far: 6964.698
Subtracting 584 from 630 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
73 can be fit into 460 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 6964.6986
If we subtract 438 from 460, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 11:
73 can be fit into 220 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 6964.69863
Deduct 219 from 220 and we're left 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 12:
The number 73 fits into 10 0 times, leaving a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 6964.69863
Deduct 0 from 10 and we're left 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.

Going ahead to step 13:
The number 73 fits into 100 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 6964.6986301
Deduct 73 from 100 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 14:
270 divided by 73 is 3 with a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 6964.69863013
If we take 219 away from 270, we end up 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.

Our division results in 6964.69863013 with a remaining 5.1e-08.
